Core
Core contains common libraries used across the synapse Go repositories.
Directory Structure
root ├── bytemap: Implements a map using `[]rune` or `[]byte` instead of `string` ├── commandline: Provides utilities for creating an interactive shell command for a [`cli`](github.com/urfave/cli) using the [`go-prompt`](github.com/c-bata/go-prompt) package. ├── config: Contains the configuration for the core package. ├── dbcommon: Contains common database utilities used with gorm. ├── dockerutil: Provides tools for working with Docker. ├── ginhelper: Contains a set of utilities for working with the Gin framework and a set of common middleware. ├── mapmutex: Implements a map that uses a mutex to protect concurrent access. ├── merkle: Provides a go based merkle tree implementation. ├── metrics: Provides a set of utilities for working with metrics/otel tracing. ├── mocktesting: Provides a mocked tester for use with `testing.TB` ├── observer: Provides an interface for adding/removing listeners. ├── processlog: Provides a way to interact with detatched processes as streams. ├── retry: Retries a function until it succeeds or the timeout is reached. This comes with a set of backoff strategies/options. ├── server: Provides a context-safe server that can be used to start/stop a server. ├── testsuite: Provides a wrapper around testify/suite. ├── threaditer: Provides a thread-safe generic iterator for a slice.

Variables ¶
var LogLevels = []zapcore.Level{zapcore.DebugLevel, zapcore.InfoLevel, zapcore.WarnLevel, zapcore.ErrorLevel, zapcore.DPanicLevel, zapcore.PanicLevel, zapcore.FatalLevel}
LogLevels stores available log levels in serverity order.
Functions ¶
func ArePointersEqual ¶ added in v0.0.52
func ArePointersEqual(a, b interface{}) bool
ArePointersEqual returns true if the given pointers are equal. Will return false if either of the given values are not pointers. nolint: cyclop, forcetypeassert
func BigToDecimals ¶ added in v0.1.2
BigToDecimals converts a big to decimals
func BytesToSlice ¶
BytesToSlice converts a 32 bit array to a slice slice.
func ChunkSlice ¶ added in v0.0.82
ChunkSlice takes a slice of any ordered type (like int, float64, string, etc.) and divides it into chunks of a specified size.
func CopyBigInt ¶
CopyBigInt creates a copy of a big int without mutating the original.
func CopyFile ¶ added in v0.0.74
CopyFile copies a file from src to dest and preserves its permissions.
func CopyPointer ¶ added in v0.1.4
func CopyPointer[T any](originalPtr *T) *T
CopyPointer is a generic function that takes a pointer of any type and returns a new pointer to a new value of the same type.
func ExpandOrReturnPath ¶ added in v0.0.6
ExpandOrReturnPath expands a homedir path, if it can't be expanded, the original dir is returned since on these systems homedir cannot be used anyway.
func GetEnv ¶
GetEnv gets an environment variable. If it is not present, the default variable is used.
func GetEnvBool ¶ added in v0.0.70
GetEnvBool gets an environment variable as a bool. If not found the default value is used.
func GetEnvInt ¶
GetEnvInt gets an environment variable as an int. if not found or cast the defaultVal is returned.
func IsTest ¶ added in v0.0.11
func IsTest() bool
IsTest returns true if the current process is a test.
func PtrSlice ¶ added in v0.0.61
func PtrSlice[T any](slice []T) []*T
PtrSlice converts every item in the slice to a pointer.
Example ¶
package main
import (
"fmt"
"github.com/ethereum/go-ethereum/common"
"github.com/synapsecns/sanguine/core"
"reflect"
)
func main() {
res := core.PtrSlice([]common.Hash{})
fmt.Println(reflect.TypeOf(res))
}
Output: []*common.Hash
func PtrTo ¶ added in v0.0.32
func PtrTo[T any](v T) *T
PtrTo returns a pointer to the given value.
Example ¶
package main
import (
"fmt"
"github.com/ethereum/go-ethereum/common"
"github.com/synapsecns/sanguine/core"
"reflect"
)
func main() {
res := core.PtrTo(common.Hash{})
fmt.Println(reflect.TypeOf(res))
}
Output: *common.Hash
func RandomItem ¶ added in v0.0.36
RandomItem is a generic function to get a random item from a slice.
func SleepWithContext ¶ added in v0.0.43
SleepWithContext will wait for the timer duration to expire, or the context is canceled. Which ever happens first. If the context is canceled the Context's error will be returned.
Expects Context to always return a non-nil error if the Done channel is closed. Note: this was taknen from the aws sdk, but modified to avoid the dependency in core.
