Trait FromInvocation 

pub trait FromInvocation: Sized {
    // Required method
    fn from_invocation(
        input: &InvocationInput<'_>,
        name: &str,
        required: bool,
    ) -> Result<Self, InputRejection>;
}

Decodes one typed handler argument from an invocation.

Required Methods

fn from_invocation( input: &InvocationInput<'_>, name: &str, required: bool, ) -> Result<Self, InputRejection>

Extracts one handler argument.

Errors

Returns a stable rejection when the value is missing, cannot be decoded, or fails model validation.

Dyn Compatibility

This trait is not dyn compatible.

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