Method build

crates/wasi/src/ctx.rs:453–473

Uses the configured context so far to construct the final [`WasiCtx`]. Note that each `WasiCtxBuilder` can only be used to "build" once, and calling this method twice will panic. # Panics Panics if this method is called twice. Each [`WasiCtxBuilder`] can be used to create only a single [`WasiCtx`]. Repeated usage of this method is not allowed and should use a second builder instead.

    /// used to create only a single [`WasiCtx`]. Repeated usage of this method
    /// is not allowed and should use a second builder instead.
