Struct wasmtime_wasi::WasiCtx

pub struct WasiCtx { /* private fields */ }

Implementations

Make a new WasiCtx with some default settings.

File descriptors 0, 1, and 2 inherit stdin, stdout, and stderr from the host process.
Environment variables are inherited from the host process.

To override these behaviors, use WasiCtxBuilder.
