Enum Concession 

pub enum Concession {
    Refuse,
    Accept,
}

What to do when the document cannot be converted faithfully.

One variant per kind of compromise the pipeline knows how to make, plus Concession::Refuse, which is always available and is the default. The enum is deliberately not bool: “rasterize it” and “drop it” are different answers with different consequences, and a caller who wants one and not the other must be able to say so.

Variants

Refuse

Do not convert. The conversion stops and reports why.

The default at every decision point, because a caller who has not thought about a compromise has not agreed to it.

Accept

Make the compromise, and record it in Conversion::compromises.

Implementations

impl Concession

pub const fn accepts(self) -> bool

Whether this concession permits the compromise.

Trait Implementations

impl Eq for Concession

impl Hash for Concession

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

impl Ord for Concession

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for Concession

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

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl PartialOrd for Concession

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool
