For more details, check out the docs.

DefaultLeafCache
LeafRenderer
LeafRenderer implements the full Leaf language pipeline.
LeafSources
An opaque object holding named LeafSource adherants specifying a default search order.

LeafCache
LeafCache provides blind storage for compiled LeafAST objects.
LeafDataRepresentable
Capable of being encoded as LeafData.
LeafSource
Public protocol to adhere to in order to provide template source originators to LeafRenderer
LeafTag
Create custom tags by conforming to this protocol and registering them.
UnsafeUnescapedLeafTag
Tags conforming to this protocol do not get their contents HTML-escaped.

LeafAST
LeafAST represents a “compiled,” grammatically valid Leaf template (which may or may not be fully resolvable or erroring)
LeafConfiguration
General configuration of Leaf
LeafContext
LeafData
LeafData is a “pseudo-protocol” wrapping the physically storable Swift data types Leaf can use directly
LeafError
LeafError reports errors during the template rendering process, wrapping more specific errors if necessary during Lexing and Parsing stages.
LexerError
LexerError reports errors during the lexing stage.
NIOLeafFiles
Reference and default implementation of LeafSource adhering object that provides a non-blocking file reader for LeafRenderer

ConditionalSyntax
Constant
An integer or double constant value parameter (eg 1_000, -42.0)
LeafKeyword
Keywords are identifiers which take precedence over syntax/variable names - may potentially have representable state themselves as value when used with operators (eg, true, false when used with logical operators, nil when used with equality operators, and so forth)
LeafOperator
Mathematical and Logical operators
Parameter
An associated value enum holding data, objects or values usable as parameters to a .tag
ParameterDeclaration
