Struct CastHeader 

pub struct CastHeader {

    pub version: u32,
    pub width: u16,
    pub height: u16,
    pub timestamp: i64,
    pub command: String,
    pub src_node: String,

    pub env: BTreeMap<String, String>,
    pub ssh_user: String,
    pub local_user: String,
    pub connection_id: String,
}

The header of an asciinema cast file (Go sessionrecording.CastHeader).

Only the fields Tailscale SSH sets are modelled; the Kubernetes-proxy fields have no counterpart in this fork. Field order matches the Go struct so the emitted JSON is byte-comparable.

Fields

version: u32

asciinema file format version. Always 2.

width: u16

Terminal width in characters; non-zero for PTY sessions.

height: u16

Terminal height in characters; non-zero for PTY sessions.

timestamp: i64

Unix timestamp of when the recording started.

command: String

The command that was executed. Empty for shell sessions.

src_node: String

FQDN (MagicDNS name, no trailing dot) of the node originating the connection.

src_node_id: String

Stable node id of the node originating the connection.

src_node_tags: Vec<String>

Tags on the originating node, if it is tagged.

src_node_user_id: i64

User id of the originating node’s owner, if it is not tagged.

src_node_user: String

Login name of the originating node’s owner, if it is not tagged.

env: BTreeMap<String, String>

Session environment. Go sets only TERM.

ssh_user: String

The username as presented by the client.

local_user: String

The effective local username on the server.

connection_id: String

Identifier of the SSH connection this session belongs to; shared across sessions multiplexed on one connection.

Implementations

impl CastHeader

pub fn new(timestamp_unix: i64, term: &str) -> Self

A header for a session starting at timestamp_unix, with TERM set to term.

Go refuses to write an empty TERM (envValFromList falls back to xterm-256color), so an empty term is normalized the same way here.

pub fn to_line(&self) -> Result<Vec<u8>, Error>

The header as the cast file’s first line: its JSON encoding plus a newline.

Trait Implementations

impl Clone for CastHeader

fn clone(&self) -> CastHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CastHeader

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

Formats the value using the given formatter.

impl Default for CastHeader

fn default() -> CastHeader

Returns the “default value” for a type.

impl Eq for CastHeader

impl PartialEq for CastHeader

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for CastHeader

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
