std::env - Rust (original) (raw)
Expand description
Inspection and manipulation of the process’s environment.
This module contains functions to inspect various aspects such as environment variables, process arguments, the current directory, and various other important directories.
There are several functions and structs in this module that have a counterpart ending in os. Those ending in os will return an OsStringand those without will return a String.
Constants associated with the current target
An iterator over the arguments of a process, yielding a String value for each argument.
An iterator over the arguments of a process, yielding an OsString value for each argument.
The error type for operations on the PATH variable. Possibly returned fromenv::join_paths().
An iterator that splits an environment variable into paths according to platform-specific conventions.
An iterator over a snapshot of the environment variables of this process.
An iterator over a snapshot of the environment variables of this process.
The error type for operations interacting with environment variables. Possibly returned from env::var().
