Enum ParseFloatError 

pub enum ParseFloatError {
    Empty,
    Invalid,
    ValidationFailed(FloatError),
}

String parsing error

Contains three possible error variants:

1. Empty string after trimming whitespace
2. String cannot be parsed as a floating-point number
3. Parsing succeeded but validation failed (wraps FloatError)

Variants

Empty

String is empty after trimming whitespace

Invalid

String cannot be parsed as a valid floating-point number

ValidationFailed(FloatError)

Parsing succeeded but value validation failed

Trait Implementations

impl Clone for ParseFloatError

fn clone(&self) -> ParseFloatError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ParseFloatError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ParseFloatError

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ParseFloatError

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

Formats the value using the given formatter.

impl Error for ParseFloatError

Available on crate feature std only.

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<FloatError> for ParseFloatError

fn from(err: FloatError) -> Self

Converts to this type from the input type.

impl From<ParseFloatError> for ParseFloatError

fn from(_: ParseFloatError) -> Self

Converts to this type from the input type.

impl PartialEq for ParseFloatError

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for ParseFloatError

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for ParseFloatError
