Struct Interface 

#[repr(C)]
pub struct Interface {
    pub structure_size: u32,
    pub abi_version: u32,
    pub information: Option<ReadInformation>,
    pub probe: Option<Probe>,
    pub verification_algorithms: Option<CheckVerificationAlgorithms>,
    pub verify: Option<Verify>,
    pub digest: Option<Digest>,
    pub release: Option<Release>,
}

Function pointers use the C calling convention on every supported target. Every request receives its structure size; mismatched sizes are refused before dereferencing fields. Valid output slots are empty/zero on non-OK return; invalid output size/alignment is rejected without accessing that storage. Probe prepares the exact operation without signing or issuing any PKCS#11 call.

Fields

structure_size: u32

Size in bytes of this exact Interface representation.

abi_version: u32

Version governing the layout and service contracts.

information: Option<ReadInformation>

Optional version-information service; Fe11 requires it when selecting an engine.

probe: Option<Probe>

Optional exact-key verification preparation service.

verification_algorithms: Option<CheckVerificationAlgorithms>

Optional keyless implementation-availability service.

verify: Option<Verify>

Optional message/signature verification service; requires the preparation service.

digest: Option<Digest>

Optional whole-message hashing service; returned allocations require release.

release: Option<Release>

Optional originating-allocator release service for OwnedBytes results.
