Enum CompIdError 

#[non_exhaustive]
pub enum CompIdError {
    Empty,
    TooLong {
        len: usize,
        max_len: usize,
    },
    IllegalByte {
        byte: u8,
        position: usize,
    },
}

Rejection reasons for crate::types::CompId construction.

A CompID is written verbatim into SenderCompID (49) and TargetCompID (56) on every outbound message, so an empty value or one carrying SOH or another control byte would produce a malformed or injectable frame. Construction is the chokepoint that makes that unrepresentable.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Empty

The value is empty.

An empty CompID would encode as 49=<SOH> (or 56=<SOH>), a field with no value that FIX TagValue treats as malformed.

TooLong

The value does not fit in the fixed inline storage.

Fields

len: usize

Length of the offered value in bytes.

max_len: usize

Maximum length in bytes, crate::types::COMP_ID_MAX_LEN.

IllegalByte

The value contains a byte outside printable ASCII (0x20..=0x7e).

Fields

byte: u8

The offending byte.

position: usize

Zero-based offset of the offending byte within the value.

impl Eq for CompIdError

impl Error for CompIdError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for CompIdError

fn eq(&self, other: &CompIdError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool
