Enum IconError

pub enum IconError {
    TooLarge,
    InvalidXml(String),
    MissingViewBox,
    NonSquare(f64, f64),
    ExternalResource(String),
    DimensionsTooLarge,
    InvalidSvg(String),
    FullyTransparent,
    Allocation(u32),
}

Application-icon validation and raster allocation failures.

XML/SVG/backend messages and rejected resource strings are included verbatim and can vary with dependency versions. Match variants for control flow.

Examples

use ailloli_ui_icon::IconError;
assert_eq!(IconError::MissingViewBox.to_string(), "application icon SVG must declare a positive viewBox");

Variants

TooLarge

Source length is strictly greater than MAX_SVG_BYTES.

InvalidXml(String)

Source is not UTF-8, is malformed XML, or its root is not <svg>.

MissingViewBox

View box is absent/malformed, not four numbers, or has nonpositive size.

NonSquare(f64, f64)

Relative view-box width/height delta exceeds square tolerance.

ExternalResource(String)

A forbidden element, reference, or recognized external CSS value was found.

DimensionsTooLarge

Raw view box or parsed tree width/height exceeds 8,192 pixels.

InvalidSvg(String)

[usvg] rejected otherwise structurally prevalidated bytes.

FullyTransparent

A 64-by-64 validation preview contained no pixel with nonzero alpha.

Allocation(u32)

Square RGBA pixmap allocation failed for the normalized side length.

Trait Implementations

impl Debug for IconError

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

Formats the value using the given formatter.

impl Display for IconError

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

Formats the value using the given formatter.

impl Error for IconError

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.
