Struct SizeParams 

pub struct SizeParams {
    pub design_size: u16,
    pub identifier: u16,
    pub name_entry: u16,
    pub range_start: u16,
    pub range_end: u16,
}

Fields

design_size: u16

The first value represents the design size in 720/inch units (decipoints).

The design size entry must be non-zero. When there is a design size but no recommended size range, the rest of the array will consist of zeros.

identifier: u16

The second value has no independent meaning, but serves as an identifier that associates fonts in a subfamily.

All fonts which share a Typographic or Font Family name and which differ only by size range shall have the same subfamily value, and no fonts which differ in weight or style shall have the same subfamily value. If this value is zero, the remaining fields in the array will be ignored.

name_entry: u16

The third value enables applications to use a single name for the subfamily identified by the second value.

If the preceding value is non-zero, this value must be set in the range 256 – 32767 (inclusive). It records the value of a field in the ‘name’ table, which must contain English-language strings encoded in Windows Unicode and Macintosh Roman, and may contain additional strings localized to other scripts and languages. Each of these strings is the name an application should use, in combination with the family name, to represent the subfamily in a menu. Applications will choose the appropriate version based on their selection criteria.

range_start: u16

The fourth and fifth values represent the small end of the recommended usage range (exclusive) and the large end of the recommended usage range (inclusive), stored in 720/inch units (decipoints).

Ranges must not overlap, and should generally be contiguous.

range_end: u16

Implementations

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'a> FontRead<'a> for SizeParams

fn read(data: FontData<'a>) -> Result<Self, ReadError>

Read an instance of Self from the provided data, performing validation.

impl FontWrite for SizeParams

fn write_into(&self, writer: &mut TableWriter)

impl Ord for SizeParams

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

This method returns an Ordering between self and other.

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