Struct OperationMetadata 

pub struct OperationMetadata {
    pub name: &'static str,
    pub description: &'static str,
    pub inputs: &'static [InputSpec],
    pub outputs: &'static [OutputSpec],
    pub requires_extensions: &'static [ExtensionSpec],
}

A static description of an Operation’s inputs, outputs, and extension requirements.

Returned by Operation::metadata and consumed by the Registry during draft-time validation. Because every field is a &'static reference, the metadata is allocation-free — an implementation typically returns a struct literal built from const arrays.

Fields

name: &'static str

The operation’s canonical name, surfaced in error messages and in logs from the Logger hook.

description: &'static str

A human-readable description of what the operation does.

inputs: &'static [InputSpec]

The operation’s declared inputs, in declaration order.

outputs: &'static [OutputSpec]

The operation’s declared outputs, in declaration order.

requires_extensions: &'static [ExtensionSpec]

The extensions the operation requires at runtime.
