Enum MatrixError 

pub enum MatrixError {
    InvalidConfig(String),
    EmptyCharset,
}

Errors produced by MatrixConfigBuilder::build and related validation routines.

Variants

InvalidConfig(String)

A configuration value failed its invariant check (e.g. fps < 1, non-finite speed, density outside [0.0, 1.0], min_trail > max_trail). The string carries a human-readable description of which field and why.

Tuple Fields

0: String

Reason the config was rejected.

EmptyCharset

The configured CharSet resolves to zero glyphs. Only CharSet::Custom with an empty Vec can hit this — the built-in variants always resolve to non-empty lists.

Trait Implementations

impl Debug for MatrixError

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

Formats the value using the given formatter.

impl Display for MatrixError

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

Formats the value using the given formatter.

impl Error for MatrixError

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.
