Enum SymbolError

Source 
pub enum SymbolError {
    TooLong(usize),
    BadChar(u8),
    MalformedSmall,
}
Expand description

Errors related to operations on the SymbolObject and SymbolSmall types.

Variants§

§

TooLong(usize)

Returned when attempting to form a SymbolSmall from a string with more than 9 characters.

§

BadChar(u8)

Returned when attempting to form a SymbolObject or SymbolSmall from a byte string with characters outside the range [a-zA-Z0-9_].

§

MalformedSmall

Malformed small symbol (upper two bits were set).
