Trait IntoHostResult 

pub trait IntoHostResult {
    // Required methods
    fn into_host_result(self) -> Result<Value, HostError>;
    fn host_type() -> HostType;
}

What a registered host closure returns: a value, or an error to raise in the script that called it.

Implemented for every IntoHostValue, so an infallible closure returns a plain i64/String/Vec<T>/…, and for Result<T, HostError>, so a fallible one returns that instead. Either way the host type checked against the host block is T’s.

Required Methods

fn into_host_result(self) -> Result<Value, HostError>

fn host_type() -> HostType

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
