pub struct BashTrap {
    pub signal: String,
    pub handler: String,
    pub reset: bool,
}

A signal trap specification.

Fields

signal: String

Signal name (EXIT, ERR, INT, TERM, HUP, etc.).

handler: String

Handler command or function name.

reset: bool

Whether to reset to default (use - as handler).

Implementations

impl BashTrap

pub fn new(signal: &str, handler: &str) -> Self

Create a new trap for a signal.

pub fn on_exit(handler: &str) -> Self

Create an EXIT trap.

pub fn on_err(handler: &str) -> Self

Create an ERR trap.

pub fn on_int(handler: &str) -> Self

Create an INT trap (Ctrl-C).

pub fn on_term(handler: &str) -> Self

Create a TERM trap.

pub fn reset(signal: &str) -> Self

Create a reset trap (ignore the signal).

pub fn emit(&self) -> String

Emit the trap statement.

Trait Implementations

impl Clone for BashTrap

fn clone(&self) -> BashTrap

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BashTrap

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

Formats the value using the given formatter.

impl PartialEq for BashTrap

fn eq(&self, other: &BashTrap) -> 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.
