Struct DeriveAttribute 

pub struct DeriveAttribute<'a> {
    pub ast: &'a Attribute,
    pub derives: Vec<Path>,
}

Fields

ast: &'a Attribute

derives: Vec<Path>

Implementations

impl<'a> DeriveAttribute<'a>

pub fn parse(ast: &'a Attribute) -> Result<Self>

pub fn parse_from(ast: &'a Attribute, effective: &Attribute) -> Result<Self>

Parse a derive attribute using the effective attribute for content extraction. ast is stored as the original attribute reference (for error spans). effective is used to parse the actual derive list.

Trait Implementations

impl<'a> Debug for DeriveAttribute<'a>

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

Formats the value using the given formatter.

impl<'a> From<DeriveAttribute<'a>> for Attribute<'a>

fn from(value: DeriveAttribute<'a>) -> Self

Converts to this type from the input type.

impl<'a> PartialEq for DeriveAttribute<'a>

fn eq(&self, other: &DeriveAttribute<'a>) -> 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<'a> TryFrom<&'a Attribute<'a>> for &'a DeriveAttribute<'a>

type Error = CodamaError

The type returned in the event of a conversion error.

fn try_from(attribute: &'a Attribute<'_>) -> Result<Self, Self::Error>

Performs the conversion.
