Struct FeatureDetector 

pub struct FeatureDetector;

Excel file feature detector

This struct provides methods to detect potentially unsupported features in Excel files before attempting operations that may fail or lose data.

Implementations

impl FeatureDetector

pub fn detect_potential_issues(_path: &str) -> Result<Vec<UnsupportedFeature>>

Detect features that may affect read/write operations

This is a placeholder for future implementation. Currently, calamine doesn’t expose detailed feature information. This would be enhanced when using a more advanced Excel library or adding custom parsing.

pub fn heuristic_check(path: &str) -> Vec<UnsupportedFeature>

Check if a file is likely to contain unsupported features

This is a heuristic check based on file extension and size. Complex Excel files (large, multiple sheets) are more likely to have unsupported features.

pub fn validate_for_write(path: &str) -> Result<()>

Validate that a file doesn’t contain features that would prevent write operations
