ConstantDescriptor

Struct ConstantDescriptor

pub struct ConstantDescriptor {
    pub name: &'static str,
    pub ty: &'static str,
    pub value: &'static str,
    pub docs: &'static str,
}
Expand description

Public-facing program constant.

Mirrors Anchor’s #[constant] IDL surface. Carries the source-level name, the stringified Rust type, and the stringified initializer expression, so off-chain consumers can reconstruct the value without the program crate as a build-time dependency.

Emitted by #[hopper::constant] as a sibling pub const next to the original declaration; collected into a &'static [ConstantDescriptor] slice by the program author (or by the hopper::program! macro) and passed to an IDL emitter via AnchorIdlWithConstants.

Fields§

§name: &'static str

Constant name, e.g. "MAX_DEPOSIT".

§ty: &'static str

Stringified Rust type, e.g. "u64" or "[u8; 32]".

§value: &'static str

Stringified initializer expression, e.g. "1_000_000".

§docs: &'static str

Optional doc-comment text.
