Struct ExecutableIdentity 

pub struct ExecutableIdentity {
    pub path: PathBuf,
    pub mtime: u64,
    pub size: u64,
}

The identity of the file an executable was started from: where it is, and the mtime and size of the file at that path. A server outlives its own binary — a rebuild replaces the file under a process that keeps serving the code it loaded hours ago — and nothing about the process itself says so. This is what makes that visible.

use majordomus_cli::lease::ExecutableIdentity;
let recorded = ExecutableIdentity { path: "/opt/majordomus".into(), mtime: 1_700_000_000, size: 42 };
let text = serde_json::to_string(&recorded).unwrap();
assert_eq!(serde_json::from_str::<ExecutableIdentity>(&text).unwrap(), recorded);

Fields

path: PathBuf

The path the process was started from.

mtime: u64

The file’s modification time, seconds since the epoch.

size: u64

The file’s size in bytes.

Implementations

impl ExecutableIdentity

pub fn replaced(&self) -> Option<String>

Has the file at the recorded path been replaced or removed since it was recorded? The reason, for a reader; None when the same file is still there.

use majordomus_cli::lease::ExecutableIdentity;
let gone = ExecutableIdentity { path: "/nowhere/majordomus".into(), mtime: 1, size: 1 };
assert!(gone.replaced().unwrap().contains("no longer on disk"));

Trait Implementations

impl Clone for ExecutableIdentity

fn clone(&self) -> ExecutableIdentity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExecutableIdentity

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ExecutableIdentity

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for ExecutableIdentity

impl JsonSchema for ExecutableIdentity

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for ExecutableIdentity

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
