Struct ddbug_parser::Size

pub struct Size(_);

An optional size.

This is similar to Option<u64>, but uses u64::MAX to encode the None case.

Implementations

impl Size

pub fn new(size: u64) -> Size

Create a known size value.

pub fn none() -> Size

Create an unknown or absent size value.

pub fn is_none(self) -> bool

Return true if the size is unknown or absent.

pub fn is_some(self) -> bool

Return true if the size is known.

pub fn get(self) -> Option<u64>

Return the size.

Trait Implementations

impl Clone for Size

pub fn clone(&self) -> Size

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Size

impl Debug for Size

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

impl Eq for Size

impl From<Option<u64>> for Size

pub fn from(size: Option<u64>) -> Size

Performs the conversion.

impl Ord for Size

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

This method returns an Ordering between self and other.

#[must_use]pub fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]pub fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

impl PartialEq<Size> for Size

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

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

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

This method tests for !=.

impl PartialOrd<Size> for Size

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

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

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

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

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

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

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

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

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

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