Struct StructReader 

pub struct StructReader<'b, 'r> { /* private fields */ }

Implementations

impl<'b, 'r> StructReader<'b, 'r>

pub fn get(&self, id: u16) -> Result<Option<Ref<'b, 'r>>>

Read a field by its stable ID. Ok(None) means absent — either the writer didn’t set it, or the writer’s schema doesn’t have it at all.

pub fn get_or_default(&self, id: u16) -> Result<Option<Ref<'b, 'r>>>

Like get, but if the field is absent and the reader schema gives it a custom default, return that default value instead of None. Presence is unchanged — get still reports the raw wire state — so this is a read-time convenience layered on top.

pub fn struct_def(&self) -> &'r StructDef

The reader-schema definition of this struct (field names for self-description).

pub fn get_bool(&self, id: u16) -> Result<Option<bool>>

Typed getter for bool fields.

pub fn get_u8(&self, id: u16) -> Result<Option<u8>>

Typed getter for u8 fields.

pub fn get_u16(&self, id: u16) -> Result<Option<u16>>

Typed getter for u16 fields.

pub fn get_u32(&self, id: u16) -> Result<Option<u32>>

Typed getter for u32 fields.

pub fn get_u64(&self, id: u16) -> Result<Option<u64>>

Typed getter for u64 fields.

pub fn get_i8(&self, id: u16) -> Result<Option<i8>>

Typed getter for i8 fields.

pub fn get_i16(&self, id: u16) -> Result<Option<i16>>

Typed getter for i16 fields.

pub fn get_i32(&self, id: u16) -> Result<Option<i32>>

Typed getter for i32 fields.

pub fn get_i64(&self, id: u16) -> Result<Option<i64>>

Typed getter for i64 fields.

pub fn get_f32(&self, id: u16) -> Result<Option<f32>>

Typed getter for f32 fields.

pub fn get_f64(&self, id: u16) -> Result<Option<f64>>

Typed getter for f64 fields.

pub fn get_str(&self, id: u16) -> Result<Option<&'b str>>

Typed getter for string fields (borrows the buffer).

pub fn get_bytes(&self, id: u16) -> Result<Option<&'b [u8]>>

Typed getter for bytes fields (borrows the buffer).

pub fn get_enum(&self, id: u16) -> Result<Option<u32>>

Typed getter for enum fields (raw open value).

pub fn get_struct(&self, id: u16) -> Result<Option<StructReader<'b, 'r>>>

Typed getter for nested struct fields.

pub fn get_list(&self, id: u16) -> Result<Option<ListReader<'b, 'r>>>

Typed getter for list fields.

pub fn get_map(&self, id: u16) -> Result<Option<MapReader<'b, 'r>>>

Typed getter for map fields.

pub fn get_union(&self, id: u16) -> Result<Option<UnionReader<'b, 'r>>>

Typed getter for union fields.
