Struct RuntimeConfigSnapshot 

pub struct RuntimeConfigSnapshot {
    pub entries: Vec<RuntimeConfigEntry>,
}

Stable snapshot of non-default runtime configuration visible to the process.

Fields

entries: Vec<RuntimeConfigEntry>

Sorted by key for stable JSON and machine-readable diffs.

Implementations

impl RuntimeConfigSnapshot

pub fn capture_current() -> Self

Capture all currently set FERRUM_* env overrides.

pub fn from_env_vars<I, K, V>(vars: I) -> Self

where I: IntoIterator<Item = (K, V)>, K: Into<String>, V: Into<String>,

Build a snapshot from a supplied environment map or iterator.

pub fn from_entries<I>(entries: I) -> Self

where I: IntoIterator<Item = RuntimeConfigEntry>,

Build a stable snapshot from explicit entries. Later entries for the same key replace earlier entries.

pub fn upsert( &mut self, key: impl Into<String>, effective_value: impl Into<String>, source: RuntimeConfigSource, )

Insert or replace one effective value, preserving stable key order.

pub fn upsert_entry(&mut self, entry: RuntimeConfigEntry)

Insert or replace one explicit entry, preserving stable key order.

pub fn with_entry( self, key: impl Into<String>, effective_value: impl Into<String>, source: RuntimeConfigSource, ) -> Self

Return a snapshot with one additional effective value.

Trait Implementations

impl Clone for RuntimeConfigSnapshot

fn clone(&self) -> RuntimeConfigSnapshot

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RuntimeConfigSnapshot

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

Formats the value using the given formatter.

impl Default for RuntimeConfigSnapshot

fn default() -> RuntimeConfigSnapshot

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for RuntimeConfigSnapshot

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for RuntimeConfigSnapshot

impl PartialEq for RuntimeConfigSnapshot

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
