Struct Capability 

pub struct Capability {
    pub level: ColorLevel,
    pub width: u16,
    pub is_tty: bool,
    pub unicode: bool,
    pub background: Background,
}

The full capability wall — carried by the environment, never the block.

Fields

level: ColorLevel

width: u16

Terminal width in columns, clamped to a sane band.

is_tty: bool

unicode: bool

background: Background

Implementations

impl Capability

pub fn probe() -> Capability

Probe the real environment through a sealed precedence fold (mirrors shikumi::resolve_progressive): CLICOLOR_FORCE > NO_COLOR > !is_tty > COLORTERM > TERM > none.

pub fn probe_stream(stream: Stream) -> Capability

pub const fn plain() -> Capability

The pipe/NO_COLOR/test floor: zero SGR, ASCII, 80 columns.

pub const fn fixed(level: ColorLevel, width: u16, unicode: bool) -> Capability

A fixed capability for tests/mocks at a chosen depth.
