Trait immeta::LoadableMetadata
[−]
[src]
pub trait LoadableMetadata: Sized { fn load<R: ?Sized + BufRead>(r: &mut R) -> Result<Self>; fn load_from_seek<R: ?Sized + BufRead + Seek>(r: &mut R) -> Result<Self> { ... } fn load_from_file<P: AsRef<Path>>(path: P) -> Result<Self> { ... } fn load_from_buf(buf: &[u8]) -> Result<Self> { ... } }
Provides several convenience functions for loading metadata from various sources.
Required Methods
fn load<R: ?Sized + BufRead>(r: &mut R) -> Result<Self>
Loads the implementing type from the given buffered input stream.
Provided Methods
fn load_from_seek<R: ?Sized + BufRead + Seek>(r: &mut R) -> Result<Self>
Loads the implementing type from the given buffered and seekable input stream.
Delegates to LoadableMetadata::load()
method by default. Implementations
may override this behavior if their respective image format may be parsed
more efficiently with seeking.
fn load_from_file<P: AsRef<Path>>(path: P) -> Result<Self>
Loads the implementing type from a file specified by the given path.
Delegates to LoadableMetadata::load_from_seek()
method by default.
fn load_from_buf(buf: &[u8]) -> Result<Self>
Loads the implementing type from an in-memory buffer.
Delegates to LoadableMetadata::load_from_seek()
method by default.
