Struct PrintfTemplate 

#[non_exhaustive]
pub struct PrintfTemplate {
    pub prefix: String,
    pub width: u8,
    pub suffix: String,
}

A printf-style multi-output template. Detected by the args parser when the output filename contains %[0-9]*d. Used by Scene-shaped inputs (PDF) to fan out one file per page.

Examples: page-%03d.png → prefix=page-, width=3, suffix=.png → page-000.png, page-001.png, … out%d.jpg → prefix=out, width=0, suffix=.jpg → out0.jpg, out1.jpg, …

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

prefix: String

width: u8

suffix: String

Implementations

impl PrintfTemplate

pub fn new( prefix: impl Into<String>, width: u8, suffix: impl Into<String>, ) -> Self

prefix + zero-padded index of width digits (0 = unpadded)

• suffix — the parsed form of prefix%0<width>dsuffix.

pub fn expand(&self, n: usize) -> String

Render the template at the given index.
