Struct Field 

pub struct Field {
    pub name: Arc<str>,
    pub value: Arc<str>,
    pub indent: u8,
    pub span: (usize, usize),
}

A field with its name, value, byte span, and indent level.

Fields represent individual pieces of parsed data within a packet. They form a hierarchy with three indent levels:

• Level 0: Packet headers
• Level 1: Top-level fields within a packet
• Level 2: Nested subfields (e.g., signature subpackets)

Visualization

The span field supports hex dump visualization, allowing UI code to highlight the corresponding bytes and assign colors as needed.

Fields

name: Arc<str>

The field name (e.g., “Version”, “Algorithm”, “Creation Time”).

value: Arc<str>

The field value as a human-readable string.

indent: u8

Indentation level: 0 = packet, 1 = field, 2 = subfield.

span: (usize, usize)

Byte range (start, end) in the original data.

Implementations

impl Field

pub fn new( name: impl Into<Arc<str>>, value: impl Into<Arc<str>>, indent: u8, span: (usize, usize), ) -> Self

Creates a new field with all parameters specified.

pub fn packet( name: impl Into<Arc<str>>, value: impl Into<Arc<str>>, span: (usize, usize), ) -> Self

Creates a packet-level field (indent 0).

Used for packet type headers like “Packet: Public Key”.

pub fn field( name: impl Into<Arc<str>>, value: impl Into<Arc<str>>, span: (usize, usize), ) -> Self

Creates a regular field (indent 1).

Used for top-level packet fields like “Version”, “Algorithm”.

pub fn subfield( name: impl Into<Arc<str>>, value: impl Into<Arc<str>>, span: (usize, usize), ) -> Self

Creates a subfield (indent 2).

Used for nested data like signature subpackets.

Trait Implementations

impl Clone for Field

fn clone(&self) -> Field

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Field

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

Formats the value using the given formatter.
