Enum OptParseError 

pub enum OptParseError {
    UnexpectedEndOfStream,
    OptionValueTooLong {
        capacity: usize,
        actual: usize,
    },
    TooManyOptions(usize),
    OptionDeltaReservedValue(u8),
    ValueLengthReservedValue(u8),
    OptionsExhausted,
}

Errors encounterable while parsing an option from bytes

Variants

UnexpectedEndOfStream

Reached end of stream before parsing was finished

OptionValueTooLong

Option value was longer than the fixed capacity

Fields

capacity: usize

actual: usize

TooManyOptions(usize)

Parsed more options than reserved capacity

OptionDeltaReservedValue(u8)

Option Delta was set to 15, which is invalid.

ValueLengthReservedValue(u8)

Value Length was set to 15, which is invalid.

OptionsExhausted

Not a true failure case; only means we tried to read the payload marker byte (0xFF) as an option header.

Trait Implementations

impl Clone for OptParseError

fn clone(&self) -> OptParseError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OptParseError

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

Formats the value using the given formatter.

impl PartialEq for OptParseError

fn eq(&self, other: &OptParseError) -> 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 PartialOrd for OptParseError

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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