Enum retroimg::ResolutionError

source · [−]

pub enum ResolutionError {
    Non,
    RatioWithoutSide,
    TooMany,
}

Variants

`Non`

not enough components to resolve output resolution

`RatioWithoutSide`

‘width’ or ‘height’ are required alongside ‘pixel_ratio’

`TooMany`

‘pixel_ratio’, ‘width’ and ‘height’ cannot be used together
