Host

wasmtime_wasi::p3::bindings::cli::exit

Trait Host 

Source 
pub trait Host {
    // Required methods
    fn exit(&mut self, status: Result<(), ()>) -> Result<()>;
    fn exit_with_code(&mut self, status_code: u8) -> Result<()>;
}
Available on crate feature p3 only.

Required Methods§

Source

fn exit(&mut self, status: Result<(), ()>) -> Result<()>

Exit the current instance and any linked instances.

Source

fn exit_with_code(&mut self, status_code: u8) -> Result<()>

Exit the current instance and any linked instances, reporting the specified status code to the host.

The meaning of the code depends on the context, with 0 usually meaning “success”, and other values indicating various types of failure.

This function does not return; the effect is analogous to a trap, but without the connotation that something bad has happened.

Dyn Compatibility§

This trait is dyn compatible.

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