Enum MicroError 

pub enum MicroError {
    InvalidName(String),
    InvalidSize(String),
    InvalidAlt(String),
    InvalidFallback(String),
    Manifest(String),
    Limit(String),

}

Why an asset, a package or a lookup was rejected. Messages name the offending value and, where it helps, what would be accepted.

Variants

InvalidName(String)

InvalidFallback(String)

A fallback that does not fit the asset’s cells, or holds whitespace or control characters.

Manifest(String)

A malformed or unsupported manifest or pack file.

Limit(String)

UnknownAsset(String)

impl Eq for MicroError

impl Error for MicroError

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 PartialEq for MicroError

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

Equality operator ==.

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

Inequality operator !=.
