Struct Derivation 

pub struct Derivation {
    pub name: String,
    pub version: Version,
    pub package_id: PackageId,
    pub inputs: Vec<DerivationRef>,
    pub build: BuildScript,
    pub cache_key: ContentHash,
}

One derivation in the renderer’s output graph. Build system agnostic.

Fields

name: String

version: Version

package_id: PackageId

Source package this derivation was emitted for (one-to-one).

inputs: Vec<DerivationRef>

Inputs the build needs (resolved at the renderer’s layer).

build: BuildScript

Ordered build steps the build system executes.

cache_key: ContentHash

Canonical hash for cache-backend lookup. Computed by the renderer over the derivation’s content-addressed inputs + build script — so a cache backend can answer “has this already been built?” without consulting the source.

Trait Implementations

impl Clone for Derivation

fn clone(&self) -> Derivation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Derivation

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Derivation

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Derivation

impl PartialEq for Derivation

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
