Struct Fingerprint 

pub struct Fingerprint {
    pub len: u64,
    pub modified: Option<SystemTime>,
    pub identity: FileIdentity,
    pub observed: SystemTime,
    pub content: ContentHash,
}

What a regular file looked like when it was read: its stat fields, the moment that stat was taken, and a fingerprint_bytes hash of its contents.

Fields

len: u64

File size in bytes.

modified: Option<SystemTime>

Modification time, when the platform reports one.

identity: FileIdentity

Inode-level identity; all fields are None off Unix.

observed: SystemTime

When the stat was taken.

content: ContentHash

Hash of the bytes that were read.

Implementations

impl Fingerprint

fn stat_matches(&self, metadata: &Metadata) -> bool

pub fn is_racy(&self) -> bool

Whether the file was modified within RACY_WINDOW of the moment the fingerprint was taken, or has no modification time at all, so a matching stat is not proof that the contents are unchanged.

Trait Implementations

impl Clone for Fingerprint

fn clone(&self) -> Fingerprint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Fingerprint

impl Debug for Fingerprint

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

Formats the value using the given formatter.

impl Eq for Fingerprint

impl PartialEq for Fingerprint

fn eq(&self, other: &Fingerprint) -> 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.
