pub const VT_CUSTOM_METADATA: VOffsetT[src]

pub fn name(&self) -> Option<&'a str>[src]

Name is not required, in i.e. a List

pub fn nullable(&self) -> bool[src]

Whether or not this field can contain nulls. Should be true in general.

pub fn type_type(&self) -> Type[src]

pub fn type_(&self) -> Option<Table<'a>>[src]

This is the type of the decoded value if the field is dictionary encoded.

pub fn dictionary(&self) -> Option<DictionaryEncoding<'a>>[src]

Present only if the field is dictionary encoded.

pub fn children(&self) -> Option<Vector<'a, ForwardsUOffset<Field<'a>>>>[src]

children apply only to nested data types like Struct, List and Union. For primitive types children will have length 0.

    &self
) -> Option<Vector<'a, ForwardsUOffset<KeyValue<'a>>>>[src]
