Functions

func HasVersion added in v1.56.0 

func HasVersion(remote string) bool

HasVersion returns true if it looks like the passed filename has a timestamp on it.

Note that the passed filename's timestamp may still be invalid even if this function returns true.

StartLargeFileRequest (b2_start_large_file) Prepares for uploading the parts of a large file.

If the original source of the file being uploaded has a last modified time concept, Backblaze recommends using src_last_modified_millis as the name, and a string holding the base 10 number number of milliseconds since midnight, January 1, 1970 UTC. This fits in a 64 bit integer such as the type "long" in the programming language Java. It is intended to be compatible with Java's time long. For example, it can be passed directly into the Java call Date.setTime(long time).

If the caller knows the SHA1 of the entire large file being uploaded, Backblaze recommends using large_file_sha1 as the name, and a 40 byte hex string representing the SHA1.

Example: { "src_last_modified_millis" : "1452802803026", "large_file_sha1" : "a3195dc1e7b46a2ff5da4b3c179175b75671e80d", "color": "blue" }

	Name            string            `json:"fileName"`        // The name of this file, which can be used with b2_download_file_by_name.
	AccountID       string            `json:"accountId"`       // The identifier for the account.
	BucketID        string            `json:"bucketId"`        // The unique ID of the bucket.

type Timestamp 

type Timestamp time.Time

Timestamp is a UTC time when this file was uploaded. It is a base 10 number of milliseconds since midnight, January 1, 1970 UTC. This fits in a 64 bit integer such as the type "long" in the programming language Java. It is intended to be compatible with Java's time long. For example, it can be passed directly into the java call Date.setTime(long time).
