Enum ArtifactBytes 

pub enum ArtifactBytes<'a> {
    Borrowed(&'a [u8]),
    Owned(Vec<u8>),
}

Where a reader’s bytes live.

Mapped is only available with the mmap feature, so the default build carries no additional dependency and targets where mapping is meaningless (wasm) simply do not enable it.

Variants

Borrowed(&'a [u8])

A span the caller owns and keeps alive.

Owned(Vec<u8>)

A vector this reader owns.

Implementations

impl<'a> ArtifactBytes<'a>

pub fn as_slice(&self) -> &[u8]

Borrow the artifact bytes.

pub fn is_memory_mapped(&self) -> bool

Whether these bytes are a memory map rather than a copy in process memory.

Exposed so a caller - or a test - can assert that a path-based open actually mapped the file instead of reading it. A change that quietly relocated the copy would otherwise be indistinguishable from a fix.

Trait Implementations

impl AsRef<[u8]> for ArtifactBytes<'_>

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl<'a> Clone for ArtifactBytes<'a>

fn clone(&self) -> ArtifactBytes<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for ArtifactBytes<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> From<Cow<'a, [u8]>> for ArtifactBytes<'a>

fn from(bytes: Cow<'a, [u8]>) -> Self

Converts to this type from the input type.
