Struct Capabilities 

#[non_exhaustive]
pub struct Capabilities { /* private fields */ }

The detected current terminal capabilities.

It can be generated from Notcurses.capabilities().

Implementations

impl Capabilities

pub fn new(nc: &Notcurses) -> Self

New Capabilities from a Notcurses context.

pub fn best_blitter(&self) -> Blitter

Returns the best Blitter available, using the following rules of graceful degradation:

Pixel > Sextant > Quadrant > Half > Ascii.

pub fn can_blitter(&self, blitter: Blitter) -> bool

Returns true if the provided Blitter is among the capabilities.

pub fn halfblock(&self) -> bool

Returns true if we can reliably use Unicode half blocks.

pub fn quadrant(&self) -> bool

Returns true if we can reliably use Unicode quadrant blocks.

pub fn sextant(&self) -> bool

Returns true if we can reliably use Unicode sextant blocks.

pub fn braille(&self) -> bool

Returns true if we can reliably use Unicode Braille.

pub fn utf8(&self) -> bool

Returns true if the encoding is UTF-8.

pub fn images(&self) -> bool

Returns true if loading images is possible.

This requires that notcurse is built against FFmpeg/OIIO.

pub fn videos(&self) -> bool

Returns true if loading videos is possible.

This requires that notcurse is built against FFmpeg/OIIO.

pub fn pixel(&self) -> bool

Returns true if we can blit pixel-accurate bitmaps.

pub const fn pixel_implementation(&self) -> PixelImplementation

Returns the detected pixel-blitting implementation.

pub fn fade(&self) -> bool

Returns true if fading is possible.

pub fn truecolor(&self) -> bool

Returns true if it’s possible to directly specify RGB values per Cell, or false if it’s only possible to use palettes.

pub fn palette_change(&self) -> bool

Returns true if the “hardware” palette can be changed.

Requires the “ccc” terminfo capability, and that the number of colors supported is at least the size of the Palette structure.

pub fn palette_size(&self) -> u32

Returns the number of simultaneous colors claimed to be supported, if there is color support.

Note that several terminal emulators advertise more colors than they actually support, downsampling internally.

Trait Implementations

impl Clone for Capabilities

fn clone(&self) -> Capabilities

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Capabilities

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Capabilities

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Capabilities

fn eq(&self, other: &Capabilities) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
