Representation of SVG attribute value.

Variants

Color(RgbColor)

<color> type.

EntityRef(&'a [u8])

Reference to ENTITY. Contains only name from &name;.

Length(Length)

<length> type.

LengthList(LengthList<'a>)

<list-of-lengths> type.

IRI(&'a [u8])

<IRI> type.

FuncIRI(&'a [u8])

<FuncIRI> type.

Number(f64)

<number> type.

NumberList(NumberList<'a>)

<list-of-numbers> type.

PredefValue(ValueId)

ID of predefined value.

String(&'a [u8])

Unknown data.

Methods

impl<'a> AttributeValue<'a>

fn from_stream(eid: ElementId, aid: AttributeId, stream: &mut Stream<'a>) -> Result<AttributeValue<'a>, Error>

Converts stream data into AttributeValue.

This function supports all presentation attributes.

Errors

• Most of the Error types can occur.
• Data of unknown attribute will be parsed as AttributeValue::String, without errors.
• Fallback color for <paint> type is not supported. It will be skipped. Example: fill="#linearGradient1 #f00".

Notes

• <transform>, <path> and <style> values should be parsed using their own tokenizer's. This function will parse them as AttributeValue::String, aka ignores.

• enable-background and cursor not fully implemented. This function will try to parse a single predefined value. Other data will be parsed as AttributeValue::String.

  Library will print warning to stdout.

• viewBox will be parsed as AttributeValue::NumberList.

• <opacity> value will be bounded to 0..1 range.

• This function didn't correct most of the numeric values. If value has an incorrect data, like viewBox='0 0 -1 -5' (negative w/h is error), it will be parsed as is.

Trait Implementations

impl<'a> Clone for AttributeValue<'a>

fn clone(&self) -> AttributeValue<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> PartialEq for AttributeValue<'a>

fn eq(&self, __arg_0: &AttributeValue<'a>) -> bool

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

fn ne(&self, __arg_0: &AttributeValue<'a>) -> bool

This method tests for !=.

impl<'a> Debug for AttributeValue<'a>

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

Formats the value using the given formatter.
