Struct unix::Environ

#[repr(transparent)]pub struct Environ<'a>(pub &'a Nul<&'a Nul<u8>>);

Process environment, conventionally an array of strings of form "key=value"

Implementations

impl<'a> Environ<'a>

pub fn get<'b>(&self, s: &'b [u8]) -> Option<Option<&'a Nul<u8>>>

Get the value of the given environment variable. Returns None if the variable isn't. Returns Some(None) if the variable is, but the entry contains no '=' character.

pub fn get_str<'b>(&self, s: &'b [u8]) -> Option<Option<&'a NulStr>>

Get the value of the given environment variable. Returns None if the variable isn't, or isn't valid UTF-8. Returns Some(None) if the variable is, but the entry contains no '=' character.
