Struct protobuf_codec::field::num::FieldNum
[−]
[src]
pub struct FieldNum(_);
Field number.
Methods
impl FieldNum[src]
pub fn new(n: u32) -> Result<Self>[src]
Makes a new FieldNum instance.
Errors
The language guide says about the valid values of a field number as follows:
The smallest field number you can specify is
1, and the largest is2^29 - 1, or536,870,911. You also cannot use the numbers19000through19999, as they are reserved for the Protocol Buffers implementation
If n violates this restriction, an ErrorKind::InvalidInput error will be returned.
pub unsafe fn new_unchecked(n: u32) -> Self[src]
Makes a new FieldNum instance without checking the value.
pub fn as_u32(&self) -> u32[src]
Returns the value of the field number.
