Struct AlgorithmContext 

#[non_exhaustive]
pub struct AlgorithmContext<'a> {
    pub config_json: &'a str,
    pub host: Option<&'a dyn AlgorithmHost>,
}

Per-invocation context passed to an AlgorithmProvider.

host is an opaque AlgorithmHost callback the host populates when invoking the algorithm. Algorithms that need a concrete graph-projection / storage handle downcast through host rather than depend on uni-store / uni-algo types directly — this keeps uni-plugin free of upward dependencies.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

config_json: &'a str

JSON-serialized algorithm configuration.

host: Option<&'a dyn AlgorithmHost>

Optional opaque host handle. None when no host is bound — the algorithm may fall back to a config-only path or surface an Unbound error.

Implementations

impl<'a> AlgorithmContext<'a>

pub fn new(config_json: &'a str) -> Self

Construct an AlgorithmContext with no host bound.

pub fn with_host(self, host: &'a dyn AlgorithmHost) -> Self

Attach a host handle.

Trait Implementations

impl Debug for AlgorithmContext<'_>

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

Formats the value using the given formatter.
