Enum SymbolTable 

pub enum SymbolTable {
    Primary,
    Alternate,
    Overlay(u8),
}

An APRS symbol table selector.

Per APRS 1.0.1 §5.1, the first character of a position report’s symbol pair selects the table:

• / — Primary table (most common symbols)
• \ — Alternate table
• 0-9 or A-Z — Overlay character (displays on top of the alternate table’s symbol) used for groups and regional indicators

Variants

Primary

Primary table (/).

Alternate

Alternate table (\).

Overlay(u8)

Overlay character (digit or uppercase letter) on the alternate table.

Implementations

impl SymbolTable

pub const fn from_byte(b: u8) -> Result<Self, AprsError>

Parse a single byte into a SymbolTable.

Errors

Returns AprsError::InvalidSymbolTable for anything other than /, \, digits, or uppercase ASCII letters.

pub const fn as_byte(self) -> u8

Convert back to the wire byte.

Trait Implementations

impl Clone for SymbolTable

fn clone(&self) -> SymbolTable

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SymbolTable

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for SymbolTable

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SymbolTable

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
