Function claxon::metadata::read_metadata_block

pub fn read_metadata_block<R: ReadBytes>(
    input: &mut R, 
    block_type: u8, 
    length: u32
) -> Result<MetadataBlock>

Read a single metadata block of the given type and length from the input.

When reading a regular flac stream, there is no need to use this function directly; constructing a FlacReader will read the header and its metadata blocks.

When a flac stream is embedded in a container format, this function can be used to decode a single metadata block. For instance, the MP4 format sports a “FLAC Specific Box” which contains the block type and the raw data. This function can be used to decode that raw data.
