Struct ParamList 

pub struct ParamList {
    pub entries: Vec<(String, Option<String>)>,
}

An ordered list of parsed proj-string parameters.

Each entry is a (key, optional value) pair preserving source order, so that pipeline tokens (proj=pipeline, step, inv) keep their relative positions.

Fields

entries: Vec<(String, Option<String>)>

Ordered (key, optional value) entries.

Implementations

impl ParamList

pub fn exists(&self, key: &str) -> bool

Return true if any entry has the given key.

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

Return the string value of the first matching key.

A bare key (no =) yields Some(""); an absent key yields None.

pub fn get_f64(&self, key: &str) -> Option<f64>

Return the value of the first matching key parsed as f64.

Falls back to a leading-number parse when a strict parse fails.

pub fn get_dms(&self, key: &str) -> Option<f64>

Return the value of the first matching key parsed as DMS radians.

pub fn get_int(&self, key: &str) -> Option<i64>

Return the value of the first matching key parsed as i64.

pub fn get_bool(&self, key: &str) -> bool

Return the boolean interpretation of the first matching key.

Absent -> false. A bare key -> true. An explicit f/F/false -> false; any other present value -> true (PROJ treats any present non-false value as true).

Trait Implementations

impl Clone for ParamList

fn clone(&self) -> ParamList

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParamList

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

Formats the value using the given formatter.
