Implementations

impl HeadTable

pub fn is_bold(&self) -> bool

pub fn is_italic(&self) -> bool

Trait Implementations

impl Clone for HeadTable

fn clone(&self) -> HeadTable

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for HeadTable

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

Formats the value using the given formatter.

impl Hash for HeadTable

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, 

Feeds a slice of this type into the given Hasher.

impl PartialEq<HeadTable> for HeadTable

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

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

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

This method tests for !=.

impl PartialOrd<HeadTable> for HeadTable

fn partial_cmp(&self, other: &HeadTable) -> 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.

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

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.

impl<'a> ReadBinary<'a> for HeadTable

type HostType = HeadTable

fn read(ctxt: &mut ReadCtxt<'a>) -> Result<Self, ParseError>

impl<'a> WriteBinary<&HeadTable> for HeadTable

fn write<C: WriteContext>(
    ctxt: &mut C,
    table: &HeadTable
) -> Result<Self::Output, WriteError>

Writes the table to the WriteContext and returns a placeholder to the check_sum_adjustment field.

The check_sum_adjustment field requires special handling to calculate. See: https://docs.microsoft.com/en-us/typography/opentype/spec/head

type Output = Placeholder<U32Be, u32>

The type of the value returned by write.
