Struct mesh::payload::protobuf::FieldSizer

source ·
pub struct FieldSizer<'a> { /* private fields */ }
Expand description

Type used to compute the size of field values.

Implementations§

source§

impl<'a> FieldSizer<'a>

source

pub fn sequence(self) -> SequenceSizer<'a>

Returns a sequence sizer for sizing the field multiple times.

Panics if called while already sizing a sequence, since this would result in an invalid protobuf message.

source

pub fn write_empty(&self) -> bool

If true, encoders must write their fields even if they are empty.

source

pub fn message<F>(self, f: F)
where F: FnOnce(MessageSizer<'_>),

Computes the size for a message. Calls f with a MessageSizer to calculate the size of each field.

source

pub fn resource(self)

Computes the size for a resource.

source

pub fn varint(self, n: u64)

Computes the size for an unsigned variable-sized integer.

source

pub fn svarint(self, n: i64)

Computes the size for a signed variable-sized integer.

source

pub fn fixed64(self, n: u64)

Computes the size for a fixed 64-bit integer.

source

pub fn fixed32(self, n: u32)

Computes the size for a fixed 32-bit integer.

source

pub fn bytes(self, len: usize)

Computes the size for a byte slice.

source

pub fn packed<F>(self, f: F)
where F: FnOnce(PackedSizer<'_>),

Computes the size of a packed value. Calls f with a PackedSizer to sum the size of each element.
