Required Methods

fn get_environment<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Result<Vec<(String, String)>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Get the POSIX-style environment variables.

Each environment variable is provided as a pair of string variable names and string value.

Morally, these are a value import, but until value imports are available in the component model, this import function should return the same values each time it is called.

fn get_arguments<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Result<Vec<String>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Get the POSIX-style arguments to the program.

fn initial_cwd<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Result<Option<String>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Return a path that programs should use as their initial current working directory, interpreting . as shorthand for this.
