Struct Attributes 

pub struct Attributes {
    pub pairs: Vec<(String, String)>,
}

An ordered list of GFF3 attribute key/value pairs.

GFF3 allows multi-valued attributes (comma-separated). We keep the raw value string as-is; callers that care about multiplicity (e.g. Parent) can split on commas themselves.

Fields

pairs: Vec<(String, String)>

Implementations

impl Attributes

pub fn parse_gff3(col: &str) -> Self

Parse a GFF3 attribute column. Empty / “.” columns yield no pairs.

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

pub fn first(&self, key: &str) -> Option<&str>

First value of a potentially multi-valued attribute (split on comma).

pub fn is_empty(&self) -> bool

Trait Implementations

impl Clone for Attributes

fn clone(&self) -> Attributes

Returns a duplicate 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 Eq for Attributes

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.
