Struct LaunchDecision 

pub struct LaunchDecision {
    pub label: String,
    pub value: String,
    pub source: Option<String>,
}

One resolved launch decision, paired with the reason it was chosen.

Self::source is the whole point of the type — a value without its provenance tells a user what happened but never why, which is precisely the gap this record closes.

Fields

label: String

Short stable key naming the decision: ctx, backend, kv, cache, mtp, flags, dialect.

Stable because the GUI and the CLI dashboard both key styling off it; treat it as part of the wire contract rather than a display string.

value: String

Display-ready value, e.g. 32768 or q8_0 -> 2.1 GB, f16 would be 4.2 GB.

source: Option<String>

Where the value came from, rendered in parentheses by every consumer.

None only for decisions whose value already states its own origin — never as a shortcut for “didn’t bother”, since an unexplained value is the exact failure mode this type exists to prevent.

Implementations

impl LaunchDecision

pub fn new( label: impl Into<String>, value: impl Into<String>, source: impl Into<String>, ) -> Self

A decision whose provenance is worth stating.

pub fn bare(label: impl Into<String>, value: impl Into<String>) -> Self

A decision that is self-explanatory — see Self::source for when that is legitimate.

pub fn render_value(&self) -> String

Render as value (source), or just value when unsourced.

Trait Implementations

impl Clone for LaunchDecision

fn clone(&self) -> LaunchDecision

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LaunchDecision

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for LaunchDecision

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for LaunchDecision

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
