Struct MtimeFingerprint

pub struct MtimeFingerprint;

Expand description

Compares mtime from filesystem metadata. Cheap (one syscall), but can miss edits that land within the same second on coarse-grained filesystems, and reports false changes after git clone or cargo resets mtimes.

Trait Implementations§

impl Clone for MtimeFingerprint

fn clone(&self) -> MtimeFingerprint

Returns a duplicate of the value. Read more

1.0.0 · Source§

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

Performs copy-assignment from source. Read more

impl Debug for MtimeFingerprint

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

Formats the value using the given formatter. Read more

impl Default for MtimeFingerprint

fn default() -> MtimeFingerprint

Returns the “default value” for a type. Read more

impl Fingerprint for MtimeFingerprint

type Stamp = MtimeStamp

Opaque stamp that can be compared for equality and hashed.

fn stamp(&self, path: &Path) -> Result<Self::Stamp>

Compute the current stamp for path. Returns Err if the file is unreadable (missing, permissions, etc.) — the cache treats this as a miss that produces the caller’s error.
