Enum EnvSpec 

pub enum EnvSpec {
    Map(HashMap<String, String>),
    Template(String),
}

Polymorphic env: block. Normally a map of name → value, but in some real-world workflows the entire env: value is a template expression (e.g. env: ${{ matrix }}), where the shape resolves at runtime.

When the value is a template string, downstream code must mark the graph Partial — environment variable shape is unknown to static analysis.

The map variant uses a custom deserializer (deserialize_env_map) that stringifies scalar values. GHA accepts non-string scalars in env values (COVERAGE: false, RUST_BACKTRACE: 1, TARGET_FLAGS: (null)); a strict HashMap<String, String> rejects them and breaks 200+ real-world workflows.

Variants

Map(HashMap<String, String>)

Template(String)

Implementations

impl EnvSpec

pub fn as_map(&self) -> Option<&HashMap<String, String>>

Returns the env map if statically known, or None if it is a template expression whose shape resolves at runtime.

pub fn as_template(&self) -> Option<&str>

Returns the raw template expression, if this env: is a template.
