Struct PrettyVisitor

pub struct PrettyVisitor<'a> { /* private fields */ }

Available on crate features fmt and std and ansi only.

The visitor produced by Pretty’s MakeVisitor implementation.

Implementations

impl<'a> PrettyVisitor<'a>

pub fn new(writer: Writer<'a>, is_empty: bool) -> Self

Returns a new default visitor that formats to the provided writer.

Arguments

• writer: the writer to format to.
• is_empty: whether or not any fields have been previously written to that writer.

fn record_str(&mut self, field: &Field, value: &str)

Visit a string value.

fn record_error(&mut self, field: &Field, value: &(dyn Error + 'static))

Records a type implementing Error.

fn record_debug(&mut self, field: &Field, value: &dyn Debug)

Visit a value implementing fmt::Debug.

fn record_f64(&mut self, field: &Field, value: f64)

Visit a double-precision floating point value.

fn record_i64(&mut self, field: &Field, value: i64)

Visit a signed 64-bit integer value.

fn record_u64(&mut self, field: &Field, value: u64)

Visit an unsigned 64-bit integer value.

fn record_bool(&mut self, field: &Field, value: bool)

Visit a boolean value.

impl<'a> VisitFmt for PrettyVisitor<'a>

fn writer(&mut self) -> &mut dyn Write

Returns the formatter that this visitor writes to.

impl<'a> VisitOutput<Result<(), Error>> for PrettyVisitor<'a>

fn finish(self) -> Result

Completes the visitor, returning any output.

fn visit<R>(self, fields: &R) -> Out

where R: RecordFields, Self: Sized,

Visit a set of fields, and return the output of finishing the visitor once the fields have been visited.

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.
