Struct SourceFileHash

pub struct SourceFileHash {
    pub kind: SourceFileHashAlgorithm,
    pub(crate) value: [u8; 32],
}

The hash of the on-disk source file used for debug info and cargo freshness checks.

Fields

kind: SourceFileHashAlgorithm

value: [u8; 32]

Implementations

impl SourceFileHash

pub fn new_in_memory( kind: SourceFileHashAlgorithm, src: impl AsRef<[u8]>, ) -> SourceFileHash

pub fn new( kind: SourceFileHashAlgorithm, src: impl Read, ) -> Result<SourceFileHash, Error>

pub fn matches(&self, src: &str) -> bool

Check if the stored hash matches the hash of the string.

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

The bytes of the hash.

pub(crate) fn hash_len(&self) -> usize

Trait Implementations

impl Clone for SourceFileHash

fn clone(&self) -> SourceFileHash

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SourceFileHash

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

Formats the value using the given formatter.

impl<__D: SpanDecoder> Decodable<__D> for SourceFileHash

fn decode(__decoder: &mut __D) -> Self

impl Display for SourceFileHash

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

Formats the value using the given formatter.

impl<__E: SpanEncoder> Encodable<__E> for SourceFileHash

fn encode(&self, __encoder: &mut __E)

impl Hash for SourceFileHash

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl<__CTX> HashStable<__CTX> for SourceFileHash

where __CTX: HashStableContext,

fn hash_stable(&self, __hcx: &mut __CTX, __hasher: &mut StableHasher)

impl PartialEq for SourceFileHash

fn eq(&self, other: &SourceFileHash) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
