Enum rustfmt_nightly::string::SnippetState

enum SnippetState {
    EndOfInput(String),
    LineEnd(String, usize),
    EndWithLineFeed(String, usize),
}

Result of breaking a string so it fits in a line and the state it ended in. The state informs about what to do with the snippet and how to continue the breaking process.

Variants

EndOfInput(String)

The input could not be broken and so rewriting the string is finished.

LineEnd(String, usize)

The input could be broken and the returned snippet should be ended with a [StringFormat::line_end]. The next snippet needs to be indented.

The returned string is the line to print out and the number is the length that got read in the text being rewritten. That length may be greater than the returned string if trailing whitespaces got trimmed.

EndWithLineFeed(String, usize)

The input could be broken but a newline is present that cannot be trimmed. The next snippet to be rewritten could use more width than what is specified by the given shape. For example with a multiline string, the next snippet does not need to be indented, allowing more characters to be fit within a line.

The returned string is the line to print out and the number is the length that got read in the text being rewritten.

Trait Implementations

impl Debug for SnippetState

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

Formats the value using the given formatter.

impl PartialEq<SnippetState> for SnippetState

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl StructuralPartialEq for SnippetState

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
