Struct ParserConfig 

pub struct ParserConfig {
    pub allow_expansion: bool,
    pub strict: bool,
    pub max_expansion_depth: usize,
    pub allow_inline_comments: bool,
    pub trim_values: bool,
    pub allow_multiline: bool,
}

Controls parser behaviour. Construct with Default::default() and override individual fields as needed.

Example

use dotenv_space::core::parser::ParserConfig;

// Strict mode: only uppercase keys, no inline comments
let config = ParserConfig {
    strict: true,
    allow_inline_comments: false,
    ..Default::default()
};

Fields

allow_expansion: bool

Enable ${VAR} and $VAR substitution in values.

Default: true.

strict: bool

Enforce all-uppercase keys. Fails with ParseError::InvalidKey if a lowercase key is encountered.

Default: false.

max_expansion_depth: usize

Maximum number of recursive expansions before raising ParseError::ExpansionDepthExceeded. Prevents runaway expansion of deeply nested variable references.

Default: 10.

allow_inline_comments: bool

Strip inline comments from unquoted values. When true, the # and everything after it on unquoted lines is discarded.

Example: PORT=8080 # web server → PORT=8080.

Default: true.

trim_values: bool

Trim leading and trailing whitespace from values after all other processing. Quoted values are never trimmed — their whitespace is always preserved.

Default: true.

allow_multiline: bool

Accept values that span multiple lines. A value whose opening quote is not closed on the same line accumulates subsequent lines until the closing quote is found.

Default: true.
