Trait darling_core::FromAttributes

pub trait FromAttributes: Sized {
    // Required method
    fn from_attributes(attrs: &[Attribute]) -> Result<Self>;
}

Create an instance by parsing a list of attributes.

This trait is useful when dealing with items such as traits on traits and impl blocks, for which darling does not provide dedicated traits.

Required Methods

fn from_attributes(attrs: &[Attribute]) -> Result<Self>

Create an instance by parsing a list of attributes.

By convention, FromAttributes implementations should merge item declarations across attributes, so that the following forms are equivalent:

#[derive(Serialize)]
#[serde(rename_all = "camel_case")]
#[serde(borrow)]
pub struct SplitExample {}

#[derive(Serialize)]
#[serde(borrow, rename_all = "camel_case")]
pub struct JoinedExample {}
