Library guide · API index and notation

This page is generated from the bundled library in this checkout. Signatures and adjacent source comments are reproduced below; the linked guide explains usage, storage, failures, and platform support.

import "std/env/linux"

This is a provider or implementation package. Start with the linked guide’s application API; native declarations depend on the selected target.

Names used in signatures

Unqualified names denote this package’s types (including other source files in the same package), language built-ins, or generic parameters such as T. Qualified names use the import aliases below. These aliases belong to the library source; import a dependency yourself to use its alias in your program.

Snapshot

Struct · Source

Immutable, caller-backed copy: mutation of the process environment cannot invalidate or change this snapshot. No allocation or global pointer escapes.

pub struct Snapshot {
    // Private implementation fields omitted.
}

Snapshot.entries

Function · Source

pub fn entries(&self) -> &native.NativeList

Snapshot.len

Function · Source

pub fn len(&self) -> usize

Snapshot.at

Function · Source

pub fn at(&self, index: usize) -> Option<native.NativeString>

Snapshot.get

Function · Source

pub fn get(&self, name: &native.NativeString) -> Option<native.NativeString> from(self)

capture

Function · Source

pub fn capture(bytes: &mut[u8], wide: &mut[u16]) -> Snapshot!error.Error from(bytes, wide)

arguments

Function · Source

pub fn arguments(bytes: &mut[u8], wide: &mut[u16]) -> Snapshot!error.Error from(bytes, wide)

current_dir

Function · Source

pub fn current_dir(bytes: &mut[u8], wide: &mut[u16]) -> native.NativeString!error.Error from(bytes, wide)

Builder

Struct · Source

Explicit child environment; never changes the parent. set replaces a key atomically with respect to capacity failure. Windows compares names with the OS’s ordinal case-insensitive comparison; Unix compares native bytes.

pub struct Builder {
    // Private implementation fields omitted.
}

Builder.new

Function · Source

pub fn new(bytes: &mut[u8], wide: &mut[u16]) -> Builder from(bytes, wide)

Builder.clear

Function · Source

pub fn clear(&mut self)

Builder.copy_from

Function · Source

pub fn copy_from(&mut self, source: &Snapshot) -> void!error.Error

Builder.set

Function · Source

pub fn set(&mut self, name: &native.NativeString, value: &native.NativeString) -> void!error.Error

Builder.remove

Function · Source

pub fn remove(&mut self, name: &native.NativeString) -> bool

Builder.snapshot

Function · Source

pub fn snapshot(&self) -> Snapshot!error.Error

lookup

Function · Source

pub fn lookup(name: &native.NativeString, storage: &mut native.Workspace) -> bool!error.Error

arguments_into

Function · Source

pub fn arguments_into(storage: &mut native.ListWorkspace) -> void!error.Error

view

Function · Source

pub fn view(values: native.NativeList) -> Snapshot
