Trait fefix::prelude::Configure

pub trait Configure: Clone + Default {
    fn separator(&self) -> u8 { ... }
    fn max_message_size(&self) -> Option<usize> { ... }
    fn verify_checksum(&self) -> bool { ... }
    fn should_decode_associative(&self) -> bool { ... }
}

A provider of configuration options related to FIX encoding and decoding.

Implementing this trait

Before implementing this trait, you should look into Config, which is adequate for most uses. The only benefit of writing your own Configure implementor rather than using Config is the possibility of relying on constants in code rather than accessing struct members, which results in better inlining by LLVM. E.g.

use fefix::tagvalue::Configure;

#[derive(Default, Copy, Clone)]
struct FixInlineConfig {}

impl Configure for FixInlineConfig {
    #[inline]
    fn max_message_size(&self) -> Option<usize> {
        None
    }

    #[inline]
    fn verify_checksum(&self) -> bool {
        true
    }
}

Needless to say, think twice before polluting your codebase with such micro-optimizations.

Provided methods

fn separator(&self) -> u8

The delimiter character, which terminates every tag-value pair including the last one.

ASCII 0x1 (SOH) is the default separator character.

This setting is relevant for both encoding and decoding operations.

fn max_message_size(&self) -> Option<usize>

The maximum allowed size for any single FIX message. No restrictions are imposed when it is None.

fn verify_checksum(&self) -> bool

Determines wheather or not CheckSum(10) should be verified.

This setting has no effect when encoding FIX messages.

fn should_decode_associative(&self) -> bool

Determines whether or not the decoder needs to have access to associative FIX fields. If turned off, only linear access is possible.
