Struct Attributes

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

GTF record attributes.

Implementations

impl Attributes

pub fn is_empty(&self) -> bool

Returns whether there are any entries.

Examples

use noodles_gtf::record::Attributes;
let attributes = Attributes::default();
assert!(attributes.is_empty());

pub fn len(&self) -> usize

Returns the number of entries.

Examples

use noodles_gtf::record::Attributes;
let attributes = Attributes::default();
assert_eq!(attributes.len(), 0);

pub fn get<'a>(&'a self, key: &str) -> Option<&'a str>

Returns the value at the given key.

This returns the first match of the key.

Examples

use noodles_gtf::record::{attributes::Entry, Attributes};
let attributes = Attributes::from(vec![Entry::new("id", "g0")]);
assert_eq!(attributes.get("id"), Some("g0"));
assert!(attributes.get("source").is_none());

Trait Implementations

impl AsRef<[Entry]> for Attributes

fn as_ref(&self) -> &[Entry]

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Attributes

fn clone(&self) -> Attributes

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Attributes

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

Formats the value using the given formatter.

impl Default for Attributes

fn default() -> Attributes

Returns the “default value” for a type.

impl Display for Attributes

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

Formats the value using the given formatter.

impl From<Vec<Entry>> for Attributes

fn from(entries: Vec<Entry>) -> Self

Converts to this type from the input type.

impl FromStr for Attributes

type Err = ParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq for Attributes

fn eq(&self, other: &Attributes) -> 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 Eq for Attributes
