Struct RpnExpr 

pub struct RpnExpr(/* private fields */);

A Reverse Polish Notation expression.

Printing

An expression can be printed in one of two ways. By default, the expression is printed using Reverse Polish Notation still; however, if the # “alternate printing” flag is passed, the expression will be pretty-printed using infix notation instead, with a minimal amount of parentheses.

Implementations

impl RpnExpr

pub fn from_bytes(bytes: Vec<u8>) -> Self

Constructs a RPN expression from its byte serialization. This does not check the expression’s correctness.

pub fn bytes(&self) -> &[u8]

Retrieves the expression’s serialized bytes.

pub fn iter(&self) -> Iter<'_>

Yields an iterator over the expression’s “operations”. “Operations” may not mean what you think; refer to RpnOp for more information.
