Enum DockLayoutError 

#[non_exhaustive]
pub enum DockLayoutError {
    Syntax {
        line: usize,
        column: usize,
        message: String,
    },
    NotALayout,
    UnsupportedVersion(u64),
    Invalid(String),
}

Why a saved text could not be read. Nothing was changed; the app goes on with the arrangement it has, or the one it starts from.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Syntax

It is not well-formed text in the format.

Fields

line: usize

The line of the problem, from one.

column: usize

The column of the problem, from one.

message: String

What was wrong.

NotALayout

It is well-formed, but says nothing of being an arrangement: it has no version.

UnsupportedVersion(u64)

It was saved by a newer build, in a version this one cannot read.

Invalid(String)

It has the version, but a part of it is not what the version says.

Trait Implementations

impl Eq for DockLayoutError

impl Error for DockLayoutError

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.

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

Equality operator ==.

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

Inequality operator !=.
