Struct FileCacheKey 

pub struct FileCacheKey {
    pub file_last_modified_ns: u128,
    pub file_created_ns: Option<u128>,
    pub file_status_changed_ns: Option<u128>,

    pub file_id: Option<u64>,
    pub file_permissions_mode: u32,
    pub file_size_bytes: u64,
}

File metadata used to validate cached entries against a filesystem path.

Fields

file_last_modified_ns: u128

File modification time as nanoseconds since the Unix epoch.

file_created_ns: Option<u128>

File creation time as nanoseconds since the Unix epoch, when available.

file_status_changed_ns: Option<u128>

File status-change time as nanoseconds since the Unix epoch, when available.

file_device_id: Option<u64>

Platform device identifier, when available.

file_id: Option<u64>

Platform file identifier such as an inode, when available.

file_permissions_mode: u32

Platform permission bits or readonly flag used to invalidate stale entries.

file_size_bytes: u64

File size in bytes.

Implementations

impl FileCacheKey

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

Read file metadata from path and convert it into a cache validation key.

Trait Implementations

impl Clone for FileCacheKey

fn clone(&self) -> FileCacheKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FileCacheKey

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FileCacheKey

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for FileCacheKey

fn eq(&self, other: &FileCacheKey) -> 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 FileCacheKey

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
