Struct GetOptions 

pub struct GetOptions<'a> {
    pub path: VariantPath<'a>,
    pub as_type: Option<FieldRef>,
    pub cast_options: CastOptions<'a>,
}

Controls the action of the variant_get kernel.

Fields

path: VariantPath<'a>

What path to extract

as_type: Option<FieldRef>

if as_type is None, the returned array will itself be a VariantArray.

if as_type is Some(type) the field is returned as the specified type.

cast_options: CastOptions<'a>

Controls the casting behavior (e.g. error vs substituting null on cast error).

Implementations

impl<'a> GetOptions<'a>

pub fn new() -> Self

Construct default options to get the specified path as a variant.

pub fn new_with_path(path: VariantPath<'a>) -> Self

Construct options to get the specified path as a variant.

pub fn with_as_type(self, as_type: Option<FieldRef>) -> Self

Specify the type to return.

pub fn with_cast_options(self, cast_options: CastOptions<'a>) -> Self

Specify the cast options to use when casting to the specified type.
