Required Methods§
sourcefn get_environment(&mut self) -> Result<Vec<(String, String)>>
fn get_environment(&mut self) -> Result<Vec<(String, String)>>
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.
sourcefn get_arguments(&mut self) -> Result<Vec<String>>
fn get_arguments(&mut self) -> Result<Vec<String>>
Get the POSIX-style arguments to the program.
sourcefn initial_cwd(&mut self) -> Result<Option<String>>
fn initial_cwd(&mut self) -> Result<Option<String>>
Return a path that programs should use as their initial current working
directory, interpreting .
as shorthand for this.
