[−][src]Struct parquet::schema::types::GroupTypeBuilder
A builder for group types. All attributes are optional except the name.
Note that if not specified explicitly, None is used as the repetition of the group,
which means it is a root (message) type.
Methods
impl<'a> GroupTypeBuilder<'a>[src]
impl<'a> GroupTypeBuilder<'a>pub fn new(name: &'a str) -> Self[src]
pub fn new(name: &'a str) -> SelfCreates new group type builder with provided field name.
pub fn with_repetition(self, repetition: Repetition) -> Self[src]
pub fn with_repetition(self, repetition: Repetition) -> SelfSets Repetition for this field and returns itself.
pub fn with_logical_type(self, logical_type: LogicalType) -> Self[src]
pub fn with_logical_type(self, logical_type: LogicalType) -> SelfSets LogicalType for this field and returns itself.
pub fn with_fields(self, fields: &mut Vec<TypePtr>) -> Self[src]
pub fn with_fields(self, fields: &mut Vec<TypePtr>) -> SelfSets a list of fields that should be child nodes of this field. Returns updated self.
pub fn with_id(self, id: i32) -> Self[src]
pub fn with_id(self, id: i32) -> SelfSets optional field id and returns itself.
pub fn build(self) -> Result<Type>[src]
pub fn build(self) -> Result<Type>Creates a new GroupType instance from the gathered attributes.

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?
Create an error for a missing method specialization. Defaults to panicking with type, trait & method names. S is the encoder/decoder state type, T is the type being encoded/decoded, and the arguments are the names of the trait and method that should've been overridden. Read more
