pub struct GateProtocol;

Implementations

impl GateProtocol

pub fn parse(stdin: &str) -> Result<GateInput, GateError>

Parse the JSON payload Claude Code writes to the hook’s stdin.

pub fn read_schema_from_env() -> Result<u32, GateError>

Read KLASP_GATE_SCHEMA from the environment and parse it as a u32.

Returns GateError::SchemaMissing when the variable is not set, and GateError::Parse when the value cannot be parsed as an integer. Designed to be composed with check_schema_env.

pub fn check_schema_env(env_value: u32) -> Result<(), GateError>

Compare the env-var schema (set by the shim) with the binary’s compiled-in schema. The shim’s value is read from the environment by the caller and passed in here as a u32 — this function never touches the environment itself, keeping it pure and testable.
