Struct wasmer_ruby::Wasmer::Wasi::StateBuilder

pub struct StateBuilder;

Convenient builder API for configuring WASI.

Use the constructor to pass the arguments, environments, preopen directories and map directories, or use the associated methods to build the state step-by-steps.

Implementations

impl StateBuilder

pub fn new(program_name: String) -> Self

pub fn argument(&mut self, argument: String) -> Self

Adds an argument.

Arguments must not contain the nul (0x0) byte.

pub fn arguments(&mut self, arguments: Array<String>) -> Self

Adds multiple arguments.

Arguments must not contain the nul (0x0) byte.

pub fn environment(&mut self, key: String, value: String) -> Self

Add an environment variable pair.

Environment variable keys and values must not contain the byte = (0x3d) or null (0x0).

pub fn environments(&mut self, pairs: Hash<String, String>) -> Self

Add environment variable pairs.

Environment variable keys and values must not contain the byte = (0x3d) or null (0x0).

pub fn preopen_directory(&mut self, alias: String, value: String) -> Self

Preopen a directory with a different name exposed to the WASI.

This opens the given directories at the virtual root, /, and allows the WASI module to read and write to the given directories.

pub fn preopen_directories(&mut self, pairs: Hash<String, String>) -> Self

Preopen directories with a different name exposed to the WASI.

This opens the given directories at the virtual root, /, and allows the WASI module to read and write to the given directories.

pub fn map_directory(&mut self, alias: String, value: String) -> Self

Preopen a directory with a different name exposed to the WASI.

pub fn map_directories(&mut self, pairs: Hash<String, String>) -> Self

Preopen directories with a different name exposed to the WASI.

pub fn finalize(&mut self) -> Environment

Produces a WASI Environment based on this state builder.
