Enum BuildError 

#[non_exhaustive]
pub enum BuildError {
    Toml(Error),
    KeyParse {
        key: String,
        source: ParseKeyInputError,
    },
    InvalidTombstone {
        key: String,
    },
}

A fatal problem that prevents building a Keymap.

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.

Toml(Error)

The input was not valid TOML.

KeyParse

A key string in the [keys] table could not be parsed.

Fields

key: String

The offending key string as written.

source: ParseKeyInputError

The underlying parse error.

InvalidTombstone

A chord in a [keys] or [layers.<name>] table was assigned = true.

Only = false is a valid tombstone (unbind declaration); = true is rejected as an explicit error to prevent accidental partial unbinds. In 0.1.0 both = true and = false caused BuildError::Toml (type mismatch); 0.1.1 accepts = false but keeps = true fatal.

Fields

key: String

The offending chord string as written.

Trait Implementations

impl Debug for BuildError

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

Formats the value using the given formatter.

impl Display for BuildError

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

Formats the value using the given formatter.

impl Error for BuildError

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<Error> for BuildError

fn from(e: Error) -> Self

Converts to this type from the input type.
