Struct pica_record::primitives::Tag

pub struct Tag(/* private fields */);

A mutable tag.

Implementations

impl Tag

pub fn new(tag: &str) -> Result<Self, ParsePicaError>

Create a new Tag.

Errors

This function returns an error if the given tag is invalid.

Example

use pica_record::primitives::Tag;

let tag = Tag::new("003@")?;
assert_eq!(tag, "003@");

pub fn as_bytes(&self) -> &[u8]

Returns the Tag as a byte slice.

Example

use pica_record::primitives::Tag;

let tag = Tag::new("003@")?;
assert_eq!(tag.as_bytes(), b"003@");

pub fn write_to(&self, out: &mut impl Write) -> Result<()>

Write the Tag into the given writer.

Example

use std::io::Cursor;

use pica_record::primitives::Tag;

let mut writer = Cursor::new(Vec::<u8>::new());
let tag = Tag::new("003@")?;
tag.write_to(&mut writer);

assert_eq!(String::from_utf8(writer.into_inner())?, "003@");

Trait Implementations

impl Clone for Tag

fn clone(&self) -> Tag

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Tag

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

Formats the value using the given formatter.

impl Display for Tag

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

Formats the tag as a human-readable string.

Example

use pica_record::primitives::Tag;

let tag = Tag::new("003@")?;
assert_eq!(tag.to_string(), "003@");

impl From<TagRef<'_>> for Tag

fn from(tag: TagRef<'_>) -> Self

Create a new Tag from a TagRef.

Example

use pica_record::primitives::{Tag, TagRef};

let tag_ref = TagRef::new("003@")?;
let tag = Tag::from(tag_ref);
assert_eq!(tag, "003@");

impl PartialEq<&str> for Tag

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

Compares a Tag with a string slice.

Example

use pica_record::primitives::Tag;

let tag = Tag::new("003@")?;
assert_eq!(tag, "003@");

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 PartialEq<Tag> for TagRef<'_>

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

Compares a TagRef with a Tag.

Example

use pica_record::primitives::{Tag, TagRef};

let tag_ref = Tag::new("003@")?;
let tag = Tag::new("003@")?;
assert_eq!(tag_ref, tag);

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 PartialEq<TagRef<'_>> for Tag

fn eq(&self, other: &TagRef<'_>) -> bool

Compares a Tag with a TagRef.

Example

use pica_record::primitives::{Tag, TagRef};

let tag = Tag::new("003@")?;
let tag_ref = Tag::new("003@")?;
assert_eq!(tag, tag_ref);

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 PartialEq for Tag

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