Struct SectionInfo 

pub struct SectionInfo {
    pub section_type: SectionType,
    pub overall_position: usize,
    pub template_position: Option<usize>,
    pub content: Option<String>,
    pub operations: Option<Vec<StringOp>>,
}

Detailed information about a template section for introspection and debugging.

Provides comprehensive metadata about each section in a template, including its type, position, and content. Used by MultiTemplate::get_section_info to enable programmatic template analysis and debugging.

This struct contains all necessary information to understand both the structure and content of template sections, making it useful for tools that need to analyze or manipulate templates programmatically.

Field Details

• section_type: Whether this is a literal text section or template operation section
• overall_position: Zero-based position among all sections in the template
• template_position: Zero-based position among template sections only (None for literals)
• content: The literal text content (populated only for literal sections)
• operations: The operation sequence (populated only for template sections)

Examples

use string_pipeline::{Template, SectionType};

let template = Template::parse("Name: {upper} | Age: {lower}").unwrap();
let sections = template.get_section_info();

// First section: "Name: "
assert_eq!(sections[0].section_type, SectionType::Literal);
assert_eq!(sections[0].overall_position, 0);
assert_eq!(sections[0].template_position, None);
assert_eq!(sections[0].content, Some("Name: ".to_string()));
assert!(sections[0].operations.is_none());

// Second section: {upper}
assert_eq!(sections[1].section_type, SectionType::Template);
assert_eq!(sections[1].overall_position, 1);
assert_eq!(sections[1].template_position, Some(0));
assert!(sections[1].content.is_none());
assert_eq!(sections[1].operations.as_ref().unwrap().len(), 1);

Fields

section_type: SectionType

The type of this section (literal or template).

overall_position: usize

Position within all sections (both literal and template).

template_position: Option<usize>

Position among template sections only (None for literal sections).

content: Option<String>

Text content for literal sections (None for template sections).

operations: Option<Vec<StringOp>>

Operations for template sections (None for literal sections).
