Types and functions to work with KBFS blocks. The package is named kbfsmd rather than md to avoid clashes with existing variable names.

All errors returned by this package are wrapped with pkg/errors, and so need errors.Cause() to unwrap them.

WriterMetadataV2 stores the metadata for a TLF that is only editable by users with writer permissions.

NOTE: Don't add new fields to this type! Instead, add them to WriterMetadataExtraV2. This is because we want old clients to preserve unknown fields, and we're unable to do that for WriterMetadata directly because it's embedded in RootMetadata.

func (*WriterMetadataV2) ToWriterMetadataV3 

func (wmdV2 *WriterMetadataV2) ToWriterMetadataV3() WriterMetadataV3

ToWriterMetadataV3 converts the WriterMetadataV2 to a WriterMetadataV3.
