Crate face_verification_core 

Core types for an on-device face liveness and verification engine.

This crate is intentionally UI-agnostic and Flutter-agnostic. It should be usable from Flutter, Tauri, native Rust apps, servers, or any host that can call Rust/WASM.

Structs

BoundingBox

CapturedPhotoAnalysis

FaceAnalysis

FaceVerificationEngine

Headless verification engine. It owns the model bundle and thresholds, and is the future home for the ONNX/tract image-analysis pipeline.

FrameAnalysis

HandAnalysis

ImageInput

Landmarks

LivenessChallenge

A complete liveness challenge.

ModelAsset

One model file plus the metadata needed to wire it into a pipeline.

ModelBundle

A complete, swappable model set.

ModelValidation

NsfwScores

Point

PoseCheck

Result of validating one frame or one captured photo against a step.

SessionTickJsonResult

VerificationChecks

VerificationResult

VerificationSession

VerificationThresholds

Runtime knobs used by the liveness pipeline.

Enums

ChallengeStep

One step in a liveness challenge.

FaceVerificationError

Public error type for the core.

ModelFormat

Serialized model format accepted by the Rust runtime.

ModelRole

Role a model plays in the full image-analysis pipeline.

SessionDecision

TouchTarget

Facial target used by hand-to-face liveness checks.
