DataFrameAttrs

miniextendr_macros::dataframe_derive

Struct DataFrameAttrs

pub(crate) struct DataFrameAttrs {
    pub(crate) name: Option<Ident>,
    pub(crate) align: bool,
    pub(crate) tag: Option<String>,
    pub(crate) conflicts: Option<String>,
}

Expand description

Parsed container-level #[dataframe(...)] attributes.

Fields§

§name: Option<Ident>

Custom companion type name (default: {TypeName}DataFrame).

§align: bool

Enum alignment mode — implicit for enums, accepted but not required.

§tag: Option<String>

Tag column name for variant discriminator (also supported on structs).

§conflicts: Option<String>

Conflict resolution mode for type collisions across enum variants. Currently only “string” is supported: convert conflicting fields via ToString.

fn try_from(value: U) -> Result<T, <T as TryFrom<U>>::Error>

Performs the conversion.

impl<T, U> TryInto<U> for T
where U: TryFrom<T>,

fn try_into(self) -> Result<U, <U as TryFrom<T>>::Error>

Performs the conversion.

Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
