Variants

ExtentOverflow

The grid extent overflows the index representation.

NotEnoughElements

The storage has fewer elements than the grid requires.

Fields

required: usize

The required number of elements.

available: usize

The available number of elements.

RenderSpace(NotEnoughSpace)

The renderer’s byte-frame storage has insufficient free capacity.

RenderPositionOverflow

The positioned grid exceeds the renderer’s coordinate representation.

UnresolvedColor

A terminal color requires composition before ANSI encoding.

Fields

foreground: bool

Whether the unresolved color is the foreground color.

color: TermColor

The unresolved color.

Implementations

impl TermGridError

pub const fn not_enough_elements(required: usize, available: usize) -> Self

Creates an insufficient-element error.

pub const fn unresolved_color(foreground: bool, color: TermColor) -> Self

Creates an unresolved-color rendering error.

Trait Implementations

impl Clone for TermGridError

fn clone(&self) -> TermGridError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for TermGridError

impl Debug for TermGridError

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

Formats the value using the given formatter.

impl Display for TermGridError

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

Formats the value using the given formatter.

impl Eq for TermGridError

impl Error for TermGridError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<NotEnoughSpace> for TermGridError

fn from(err: NotEnoughSpace) -> TermGridError

Converts to this type from the input type.

impl Hash for TermGridError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for TermGridError

fn eq(&self, other: &TermGridError) -> 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.
