pub struct TextScreen;Expand description
Renders screens as plain text.
A renderer states weight however its medium can. Plain text has no weight to state, so this interpreter keeps every word and drops every emphasis, which is exactly what makes it the one to read a screen’s meaning back from.

Source§fn gauge_laws(&self) -> Result<(), Error>
fn gauge_laws(&self) -> Result<(), Error>
Checks that a gauge states a share without claiming more resolution than it has.
The laws checked are:
- a gauge occupies its stated width whatever share it states;
- no share is stated as filled before it is reached, and none is stated twice;
- nothing stated is nothing filled, and everything stated fills the whole track;
- the stated text occupies exactly one cell per counted cell.
§Errors
Returns the first violated law.

Source§fn to<R>(self) -> Rwhere
This: Into<R>,
fn to<R>(self) -> Rwhere
This: Into<R>,
A version of Into::into function that can be used to explicitly specify the target
conversion type.
use alux_sdk::*;
// `Into` requires context to infer the type,
let _: i64 = Into::into(42_i8);
// The opposite `From` requires context to infer the type,
let _: i64 = From::from(42_i8);
// `.to()` can be used in the same way as a postfix function (the same as `.into()`),
let _: i64 = 42_i8.to();
// but also with the type specified explicitly.
let _ = 42_i8.to::<i64>();
// Especially useful to chain multiple conversions inline.
let _: i64 = 42_i8.to::<i16>().to::<i32>().into();Source§impl<This> IntoIteratorExt<This> for This

Source§fn try_collect_vec<T, E>(self) -> Result<Vec<T>, E>
fn try_collect_vec<T, E>(self) -> Result<Vec<T>, E>
A variant of the try_collect and collect_vec combined function from the Itertools
library. The materialized value is a Vec inside a Result object.
Returns the first error without collecting later values.
use alux_sdk::*;
let values = [Ok::<_, &str>(1), Ok(2), Ok(3)]
.into_iter()
.try_collect_vec();
assert_eq!(values, Ok(vec![1, 2, 3]));Source§fn collect_exact<T>(self, n: usize) -> Option<Vec<T>>where
This: Iterator<Item = T>,
fn collect_exact<T>(self, n: usize) -> Option<Vec<T>>where
This: Iterator<Item = T>,
Takes exactly n elements from the iterator.
Returns Some(Vec<T>) if the iterator yields exactly n elements,
otherwise returns None.
use alux_sdk::*;
let v = [1, 2, 3];
assert_eq!(v.iter().copied().collect_exact(3), Some(vec![1, 2, 3]));
assert_eq!(v.iter().copied().collect_exact(4), None);
assert_eq!(v.iter().copied().collect_exact(2), None);Source§fn try_unzip<A, B, E>(self) -> Result<(Vec<A>, Vec<B>), E>
fn try_unzip<A, B, E>(self) -> Result<(Vec<A>, Vec<B>), E>
Efficiently splits an iterator of Result<(A, B), E> into two Vecs, short-circuiting on error.
Consumes the iterator, collecting all A elements into one vector and all B elements into another,
without first allocating an intermediate vector of tuples. Returns the tuple (Vec<A>, Vec<B>) on success,
or the first error encountered.
use alux_sdk::*;
let input = vec![Ok((1, "x")), Ok((2, "y"))];
let (xs, ys) = input.try_unzip::<_, _, ()>().unwrap();
assert_eq!(xs, vec![1, 2]);
assert_eq!(ys, vec!["x", "y"]);
