Enum Address 

pub enum Address {
    LineNumber(usize),
    Pattern(String),
    FirstLine,
    LastLine,
    Negated(Box<Address>),
    Relative {
        base: Box<Address>,

Unified address representation

Variants

LineNumber(usize)

Specific line number (e.g., 10)

Pattern(String)

Regex pattern match (e.g., /foo/)

FirstLine

First line (special address “0”)

LastLine

Last line (special address “$”)

Negated(Box<Address>)

Negated address (e.g., !10, !/pattern/)

Relative

Relative offset (e.g., /pattern/,+5)

Fields

base: Box<Address>

offset: isize

Step

Step addressing (e.g., 1~2 for every 2nd line from line 1)

Fields

start: usize

step: usize

Trait Implementations

impl Clone for Address

fn clone(&self) -> Address

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Address

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Address

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Address

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

impl Serialize for Address

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
