Struct LoadContext 

pub struct LoadContext<'a> { /* private fields */ }

Everything a loader is given for one load.

bytes is Some when an asset source (a registered .lpak bundle, say) already produced the file contents; in that case path is the requested path and may be a lumen://app/... URI rather than a filesystem location. bytes is None when the path is expected to be read from disk.

Implementations

impl<'a> LoadContext<'a>

pub fn new(path: &'a Path, bytes: Option<&'a [u8]>) -> Self

Builds a context for path, optionally carrying bytes an asset source already resolved.

pub fn path(&self) -> &'a Path

The requested path. Use it for error messages and for decoders that take a path directly.

pub fn bytes(&self) -> Option<&'a [u8]>

Bytes an asset source already resolved, or None when the loader is expected to read Self::path itself.

pub fn read_bytes(&self) -> Result<Cow<'a, [u8]>, LoadErrorKind>

The asset’s bytes: the pre-resolved ones when a source supplied them, otherwise the file read from disk.
