Struct MarkSpec 

pub struct MarkSpec {
    pub attrs: Option<HashSet<String>>,
    pub required_attrs: HashSet<String>,
}

Rules for one mark type.

Fields

attrs: Option<HashSet<String>>

Allowed attribute keys. None = any attrs allowed.

required_attrs: HashSet<String>

Attribute keys that must be present.

Implementations

impl MarkSpec

pub fn new() -> Self

An unrestricted mark spec (any attrs allowed).

pub fn attrs<I, S>(self, keys: I) -> Self

where I: IntoIterator<Item = S>, S: Into<String>,

Restrict allowed attribute keys.

pub fn required_attrs<I, S>(self, keys: I) -> Self

where I: IntoIterator<Item = S>, S: Into<String>,

Set attribute keys that must be present.

Trait Implementations

impl Clone for MarkSpec

fn clone(&self) -> MarkSpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MarkSpec

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

Formats the value using the given formatter.

impl Default for MarkSpec

fn default() -> MarkSpec

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for MarkSpec

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for MarkSpec

fn eq(&self, other: &MarkSpec) -> 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 Serialize for MarkSpec

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
