Struct CacheKey 

pub struct CacheKey {
    pub canonical_path: PathBuf,
    pub size_bytes: u64,
    pub head4k_sha256: String,
}

Composite cache key.

Fields

canonical_path: PathBuf

Canonical, symlink-resolved binary path.

size_bytes: u64

Size of the binary in bytes.

head4k_sha256: String

SHA-256 of the first 4096 bytes (or the whole file if shorter).

Implementations

impl CacheKey

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

Construct a cache key by reading metadata + the head of the binary.

Errors

Forwards I/O errors from canonicalizing the path or reading its head.

Trait Implementations

impl Clone for CacheKey

fn clone(&self) -> CacheKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CacheKey

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

Formats the value using the given formatter.

impl PartialEq for CacheKey

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