Source
pub struct Builder<'a> { /* private fields */ }
Expand description

A mutable dynamically-typed struct.

Implementations§

Source§

impl<'a> Builder<'a>

Source

pub fn get_schema(&self) -> StructSchema

Source

pub fn get(self, field: Field) -> Result<Builder<'a>>

Source

pub fn get_named(self, field_name: &str) -> Result<Builder<'a>>

Source

pub fn which(&self) -> Result<Option<Field>>

Source

pub fn has(&self, field: Field) -> Result<bool>

Source

pub fn has_named(&self, field_name: &str) -> Result<bool>

Source

pub fn set(&mut self, field: Field, value: Reader<'_>) -> Result<()>

Source

pub fn set_named(&mut self, field_name: &str, value: Reader<'_>) -> Result<()>

Source

pub fn init(self, field: Field) -> Result<Builder<'a>>

Source

pub fn init_named(self, field_name: &str) -> Result<Builder<'a>>

Source

pub fn initn(self, field: Field, size: u32) -> Result<Builder<'a>>

Source

pub fn initn_named(self, field_name: &str, size: u32) -> Result<Builder<'a>>

Source

pub fn clear(&mut self, field: Field) -> Result<()>

Clears a field, setting it to its default value. For pointer fields, this makes the field null.

Source

pub fn clear_named(&mut self, field_name: &str) -> Result<()>

Source

pub fn downcast<T: OwnedStruct>(self) -> T::Builder<'a>

Downcasts the Builder into a specific struct type. Panics if the expected type does not match the value.
