Enum gtk4::FileChooserError

#[non_exhaustive]
pub enum FileChooserError {
    Nonexistent,
    BadFilename,
    AlreadyExists,
    IncompleteHostname,
    // some variants omitted
}

These identify the various errors that can occur while calling FileChooser functions.

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.

Nonexistent

Indicates that a file does not exist.

BadFilename

Indicates a malformed filename.

AlreadyExists

Indicates a duplicate path (e.g. when adding a bookmark).

IncompleteHostname

Indicates an incomplete hostname (e.g. “http://foo” without a slash after that).

Formats the value using the given formatter.

impl Display for FileChooserError

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

Formats the value using the given formatter.

impl ErrorDomain for FileChooserError

fn domain() -> Quark

Returns the quark identifying the error domain.

fn code(self) -> i32

Gets the integer representation of the variant.

fn from(code: i32) -> Option<Self>

Tries to convert an integer code to an enum variant.

impl<'a> FromValue<'a> for FileChooserError

type Checker = GenericValueTypeChecker<FileChooserError>

Value type checker.

unsafe fn from_value(value: &'a Value) -> Self

Get the contained value from a Value.

impl Hash for FileChooserError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,
    Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for FileChooserError

fn cmp(&self, other: &FileChooserError) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<FileChooserError> for FileChooserError

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<FileChooserError> for FileChooserError

fn partial_cmp(&self, other: &FileChooserError) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

fn static_type() -> Type

Returns the type identifier of Self.

impl ToValue for FileChooserError

fn to_value(&self) -> Value

Convert a value to a Value.

fn value_type(&self) -> Type

Returns the type identifer of self.

impl ValueType for FileChooserError

type Type = FileChooserError

Type to get the Type from.
