Module terminal 

Terminal capability detection and color policy.

These helpers decide whether a stream should receive ANSI styling or interactive behavior (progress lines, prompts). They do not decide what to print — see crate::color for that.

Enums

ColorMode

Explicit color policy a CLI can expose through a --color flag.

Functions

is_stderr_terminal

Whether stderr is attached to an interactive terminal.

is_stdin_terminal

Whether stdin is attached to an interactive terminal.

is_stdout_terminal

Whether stdout is attached to an interactive terminal.

resolve_color

Resolve whether color should be enabled for a stream, given an explicit ColorMode policy and whether that stream is a TTY.

stderr_supports_color

Whether stderr output should be colorized under the Auto policy: a TTY and no NO_COLOR override.

stdout_supports_color

Whether stdout output should be colorized under the Auto policy: a TTY and no NO_COLOR override.
