Struct FileSignature 

pub struct FileSignature {
    pub content_hash: Option<String>,
    pub mtime: SystemTime,
    pub size: u64,
    pub permissions: u32,
    pub is_dir: bool,
    pub is_symlink: bool,
}

File signature for change detection Uses a combination of hash and metadata for fast comparison

Fields

content_hash: Option<String>

Blake3/SHA256 hash of file contents (for files < 10MB) For larger files or directories, this is None

mtime: SystemTime

Last modification time

size: u64

File size in bytes

permissions: u32

File permissions (Unix mode)

is_dir: bool

Is this a directory?

is_symlink: bool

Is this a symlink?

Implementations

impl FileSignature

pub fn from_path(path: &Path) -> Result<Self>

Create a signature from a path

pub fn quick_changed(&self, other: &Self) -> bool

Quick check if file might have changed (without hashing)

pub fn changed(&self, other: &Self) -> bool

Full check if file has changed (including hash if available)

Trait Implementations

impl Clone for FileSignature

fn clone(&self) -> FileSignature

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FileSignature

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FileSignature

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for FileSignature

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

impl Serialize for FileSignature

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
